IEC Environmental Enclosure Ratings for Global Applications

Comparison of NEMA Type Numbers to IEC Classification Designations

IEC enclosures use a two digit numberingsystem to define the degree of protectionthey provide. The first digit specifies thedegree of protection against incidental con-tact and penetration of solid objects. Thesecond digit specifies the level of protectionagainst the ingress of water.

Example: An IP65 enclosure is dust tightand protected against water jets. An IP66enclosure is dust tight and protectedagainst powerful water jets.

First Numeral Second Numeral

Special Contactor Utilization Categories

Some contactors also have ratings for thefollowing specialty utilization categories.

For specific applications, please contactyour local Siemens sales office.

Electrical Quantities Symbols According to DIN,VDE and IEC

Contactors designed for interna-tional applications are tested andrated per IEC 947-4. The IEC rat-ing system is broken down intodifferent utilization categories thatdefine the value of the currentthat the contactor must make,maintain, and break. The follow-ing category definitions are themost commonly used for IECContactors.

Ratings for Siemens contactorsper these categories can befound in Section 3.

AC Categories

AC-1

This applies to all AC loadswhere the power factor is at least0.95. These are primarily non-inductive or slightly inductiveloads. Breaking remains easy.

AC-3

This category applies to squirrelcage motors where the breakingof the power contacts wouldoccur while the motor is running.On closing, the contactor experi-ences an inrush which is 5 to 8times the nominal motor current,and at this instant, the voltage atthe terminals is approximately20% of the line voltage. Breakingremains easy.AC-4

This applies to the starting andbreaking of a squirrel cage motorduring an inch or plug reverse.On energization, the contactorcloses on an inrush currentapproximately 5 to 8 times thenominal current. On de-energiza-tion, the contactor breaks thesame magnitude of nominal cur-rent at a voltage that can beequal to the supply voltage.Breaking is severe.

DC Categories

DC-1

This applies to all DC loadswhere the time constant (L/R) isless than or equal to one msec.These are primarily noninductiveor slightly inductive loads.DC-2

This applies to the breaking ofshunt motors while they are run-ning. On closing, the contactormakes the inrush current around2.5 times the nominal rated cur-rent. Breaking is easy.DC-3

This applies to the starting andbreaking of a shunt motor duringinching or plugging. The timeconstant shall be less than orequal to 2 msec. On energiza-tion, the contactor sees currentsimilar to that in Category DC-2.On de-energization, the contactorwill break around 2.5 times the

starting current at a voltage thatmay be higher than the line volt-age. This would occur when thespeed of the motor is lowbecause the back e.m.f. is low.Breaking is severe.DC-5

This applies to the starting andbreaking of a series motor duringinching or plugging. The timeconstant being less than or equalto 7.5 msec. On energization, thecontactor sees about 2.5 timesthe nominal full load current. Onde-energization, the contactorbreaks the same amount of cur-rent at a voltage which can beequal to the line voltage.Breaking is severe.

1)Hermetic refrigerant compressor motor is a combina-tion consisting of a compressor and a motor, both ofwhich are enclosed in the same housing, with noexternal shaft or shaft seals, the motor operating inthe refrigerant.

Full load ampere ratings ofmotors vary depending upon anumber of factors. The full loadcurrents listed above are “aver-age values” for horsepower ratedmotors of several manufacturersat the most commonly rated volt-ages and speeds. These “aver-age values” along with the similarvalues listed in the N.E.C. shouldbe used as a guide only forselecting suitable componentsfor the motor branch circuit. Therated full load current shown on

the motor nameplate may varyconsiderably from the listedvalue, depending on the speci-fied motor design. Note: RPM shown for 60Hz motors.For 50Hz motors, multiply the 60HZFLA value by 1.2.

Overload Relay Selection Multi-

Speed/Part-Winding/Wye-Delta

Special attention should be givento the selection of the overloadrelay adjustment range for multi-speed, part-winding and wye-delta controllers, as follows:

Multi-Speed Controllers: Eachspeed requires a separate set ofoverloads. The adjustment rangemust be selected on the basis ofthe full-load current for each par-ticular speed.

Part-Winding Controllers: Eachwinding of the motor must haveits own set of overloads. Theadjustment range should beselected on the basis of one-halfthe motor full-load current; that is,the full load current of each wind-ing current.

Wye-Delta Controllers: Only oneset of overloads is required.Since the overload relay is locat-ed electrically “inside the deltaconnection,” the adjustmentrange must be selected on thebasis of the full-load motor cur-rent (delta connection) dividedby 1.73.

Single Phase: See page 8/150for ampere ratings of singlephase AC induction motors.

Average Efficiency and Power Factor Values ofMotors

When the actual efficiencies and power fac-tors of the motors to be controlled are notknown, the following approximations may beused.

Fault-Current Calculation onLow-Voltage AC Systems

In order to determine the maximum interrupt-ing rate of the circuit breakers in a distribu-tion system, it is necessary to calculate thecurrent which could flow under a three-phase bolted short circuit condition. For athree-phase system the maximum availablefault current at the secondary side of thetransformer can be obtained by use of theformula:

lSC � kVA � 100KV � �3 � % Z

where:

lSC � Symmetrical RMS amperesof fault current.

kVA � Kilovolt-ampere rating oftransformers.

KV � Secondary voltage in kilovolts.

% Z � Percent impedance of primaryline and transformer.

Spring loaded terminal technique

Appendix


Spring Loaded Terminals

As an alternative to screw-type terminals, many products may be supplied with spring loaded terminals. With this screwless connection technique, the wires areclamped securely against shock and vibration by a spring clamp. Solid, stranded and finely-stranded wires can be connected with or without end sleeves.

Each terminal connection is equipped with two independently operated spring clamps. Each spring can accept one wire. The clamping force of the spring automatically adjusts to the size of the wire and compensates for any deformation of the wire, such as settling of the strands. The flat clamping face of thespring presses the wire against the current bar without damaging the wire. To prevent stranded or finely-stranded wire from being divided, the end can betinned or amalgamated using ultrasound.

The terminal is opened by inserting the screwdriver. The wire is then inserted and will remain clamped after the screwdriver is removed (see below). The chromium-nickel steel of the spring clamp provides corrosion-resistant contact of the wire-end in the clamp.

Advantages:• Quick: The connection is made easily without the need to add on wire end sleeves or torque down terminal screws—reducing wiring time• Reliable: The terminal is gas-tight and resistant to shock and vibration—for maximum contact reliability• Maintenance-free: With the spring loaded terminals, there is no need to inspect the connections following transport—eliminating time-consuming

and costly inspection

Step 1:Insert screwdriver;spring opens.

Step 2:The screwdriver holds the spring open;insert the wire.

Step 3:Remove the screwdriver; the springcloses and the wire is securely clamped.

Standard terms andconditions of sale (10/1/2004)

AppendixSiemens Energy & Automation, Inc. (Seller)


1. WARRANTY - (a) Seller warrants that on the date of shipment the goods are of

the kind and quality described herein and are free of non-conformities in workmanship

and material. This warranty does not apply to goods delivered by Seller but

manufactured by others.

(b) Buyer's exclusive remedy for a nonconformity in any item of the goods shall be the

repair or the replacement (at Seller's option) of the item and any affected part of the

goods. Seller's obligation to repair or replace shall be in effect for a period of one (1)

year from initial operation of the goods but not more than eighteen (18) months from

Seller's shipment of the goods, provided Buyer has sent written notice within that

period of time to Seller that the goods do not conform to the above warranty. Repaired

and replacement parts shall be warranted for the remainder of the original period of

notification set forth above, but in no event less than 12 months from repair or

replacement. At its expense, Buyer shall remove and ship to Seller any such

nonconforming items and shall reinstall the repaired or replaced parts. Buyer shall

grant Seller access to the goods at all reasonable times in order for Seller to

determine any nonconformity in the goods. Seller shall have the right of disposal of

items replaced by it. If Seller is unable or unwilling to repair or replace, or if repair or

replacement does not remedy the nonconformity, Seller and Buyer shall negotiate an

equitable adjustment in the contract price, which may include a full refund of the

contract price for the nonconforming goods.

(c) SELLER HEREBY DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR

IMPLIED, EXCEPT THAT OF TITLE. SPECIFICALLY, IT DISCLAIMS THE IMPLIED

WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,

COURSE OF DEALING AND USAGE OF TRADE.

(d) Buyer and successors of Buyer are limited to the remedies specified in this article

and shall have no others for a nonconformity in the goods. Buyer agrees that these

remedies provide Buyer and its successors with a minimum adequate remedy and are

their exclusive remedies, whether Buyer's or its successors' remedies are based on

contract, warranty, tort (including negligence), strict liability, indemnity, or any other

legal theory, and whether arising out of warranties, representations, instructions,

installations, or non-conformities from any cause.

(e) Note: This article 1 does not apply to any software which may be furnished by

Seller. In such cases, the attached Software License Addendum applies.

2. PATENTS - Seller shall pay costs and damages finally awarded in any suit against

Buyer or its vendees to the extent based upon a finding that the design or construction

of the goods as furnished infringes a United States patent (except infringement

occurring as a result of incorporating a design or modification at Buyer's request),

provided that Buyer promptly notifies Seller of any charge of infringement, and Seller

is given the right at its expense to settle such charge and to defend or control the

defense of any suit based upon such charge. Seller shall have no obligation hereunder

with respect to claims, suits or proceedings, resulting from or related to, in whole or in

part, (i) the use of software or software documentation, (ii) compliance with Buyer's

specifications, (iii) the combination with, or modification of, the goods after delivery by

Seller, or (iv) the use of the goods, or any part thereof, in the practice of a process.

THIS ARTICLE SETS FORTH SELLER'S ENTIRE LIABILITY WITH RESPECT TO

PATENTS.

3. PERFORMANCE; DELAYS - Timely performance by Seller is contingent upon

Buyer's supplying to Seller, when needed, all required technical information and data,

including drawing approvals, and all required commercial documentation. If Seller

suffers delay in performance due to any cause beyond its reasonable control, the time

of performance shall be extended a period of time equal to the period of the delay and

its consequences. Seller will give to Buyer notice within a reasonable time after Seller

becomes aware of any such delay.

4. SHIPMENT, TITLE AND RISK OF LOSS - Unless the delivery terms of this

contract expressly provide for F.O.B. destination, shipping/delivery will be F.O.B.

Seller's point of shipment with title to the goods and risk of loss or damage passing to

Buyer at that point. Buyer will be responsible for shipment during transit and for filing

any damage or loss claims directly with the carrier. Seller may make partial

shipments.

5. TAXES - Any applicable duties or sales, use, excise, value-added or similar taxes

will be added to the price and invoiced separately (unless an acceptable exemption

certificate is furnished).

6. TERMS OF PAYMENT - (a) Unless otherwise stated, all payments shall be in

United States dollars, and a pro rata payment shall become due as each shipment is

made. If shipment is delayed by Buyer, date of notice of readiness for shipment shall

be deemed to be date of shipment for payment purposes.

(b) On late payments, the contract price shall, without prejudice to Seller's right to

immediate payment, be increased by 1 1/2% per month on the unpaid balance, but not

to exceed the maximum permitted by law.

(c) If any time in Seller's judgment Buyer is unable or unwilling to meet the terms

specified, Seller may require satisfactory assurance or full or partial payment as a

condition to commencing or continuing manufacture or making shipment, and may, if

shipment has been made, recover the goods from the carrier, pending receipt of such

assurances.

7. NONCANCELLATION - Buyer may not cancel or terminate for convenience, or

direct suspension of manufacture, except with Seller's written consent and then only

upon terms that will compensate Seller for its engineering, fabrication and purchasing

charges and any other costs relating to such cancellation, termination or suspension,

plus a reasonable amount for profit.

8. NUCLEAR - Buyer represents and warrants that the goods covered by this

contract shall not be used in or in connection with a nuclear facility or application. If

Buyer is unable to make such representation and warranty, then Buyer agrees to

indemnify and hold harmless Seller and to waive and require its insurers to waive all

right of recovery against Seller for any damage, loss, destruction, injury or death

resulting from a “nuclear incident”, as that term is defined in the Atomic Energy Act of

1954, as amended, whether or not due to Seller's negligence.

9. LIMITATION OF LIABILITY - NEITHER SELLER, NOR ITS SUPPLIERS SHALL

BE LIABLE, WHETHER IN CONTRACT, WARRANTY, FAILURE OF A REMEDY TO

ACHIEVE ITS INTENDED OR ESSENTIAL PURPOSES, TORT (INCLUDING

NEGLIGENCE), STRICT LIABILITY, INDEMNITY OR ANY OTHER LEGAL THEORY,

FOR LOSS OF USE, REVENUE OR PROFIT, OR FOR COSTS OF CAPITAL OR OF

SUBSTITUTE USE OR PERFORMANCE, OR FOR INDIRECT, SPECIAL,

LIQUIDATED, INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR FOR ANY

OTHER LOSS OR COST OF A SIMILAR TYPE, OR FOR CLAIMS BY BUYER FOR

DAMAGES OF BUYER'S CUSTOMERS. SELLER'S MAXIMUM LIABILITY UNDER

THIS CONTRACT SHALL BE THE CONTRACT PRICE. BUYER AND SELLER

AGREE THAT THE EXCLUSIONS AND LIMITATIONS SET FORTH IN THIS

ARTICLE ARE SEPARATE AND INDEPENDENT FROM ANY REMEDIES WHICH

BUYER MAY HAVE HEREUNDER AND SHALL BE GIVEN FULL FORCE AND

EFFECT WHETHER OR NOT ANY OR ALL SUCH REMEDIES SHALL BE DEEMED

TO HAVE FAILED OF THEIR ESSENTIAL PURPOSE.

10. GOVERNING LAW AND ASSIGNMENT - The laws of the State of Georgia shall

govern the validity, interpretation and enforcement of this contract, without regard to

its conflicts of law principles. The application of the United Nations Convention on

Contracts for the International Sale of Goods shall be excluded. Assignment may be

made only with written consent of both parties; provided, however, Seller may assign

to its affiliate without Buyer's consent.

11. ATTORNEY FEES - Buyer shall be liable to Seller for any attorney fees and costs

incurred by Seller in enforcing any of its rights hereunder.

12. DISPUTES - Either party may give the other party written notice of any dispute

arising out of or relating to this contract and not resolved in the normal course of

business. The parties shall attempt in good faith to resolve such dispute promptly by

negotiations between executives who have authority to settle the dispute. If the matter

has not been resolved within 60 days of the notice, either party may initiate non-

binding mediation of the dispute.

13. STATUTE OF LIMITATIONS - To the extent permitted by applicable law, any

lawsuit for breach of contract, including breach of warranty, arising out of the

transactions covered by this contract, must be commenced not later than twelve (12)

months from the date the cause of action accrued.

14. PRICES - In the event of a price increase or decrease, the price of goods on order

will be adjusted to reflect such increase or decrease. This does not apply to a

shipment held by request of Buyer. Goods already shipped are not subject to price

increase or decrease. Orders on a bid or contract basis are not subject to this article.

Seller's prices include the costs of standard domestic packing only. Any deviation

from this standard packing (domestic or export), including U.S. Government sealed

packing, will result in extra charges. To determine such extra charges, consult Seller's

sales offices. Orders of less than $400 will be charged a $25 handling fee.

15. ADDITIONAL TERMS OF PAYMENT - Invoice payment terms are as shown on

latest discount sheets as issued from time to time. Cash discounts are not applicable

to notes or trade acceptances, to prepaid transportation charges when added to

Seller's invoices or to discountable items if there are undisputed past due items on the

account. Portions of an invoice in dispute should be deducted and the balance

remitted with a detailed explanation of the deduction. Cash discounts will only be

allowed on that portion of the invoice paid within the normal discount period.

16. CHANGES IN LAWS AND REGULATIONS - Seller's prices and timely

performance are based on all applicable laws, rules, regulations, orders, codes,

standards or requirements of governmental authorities effective on the date of Seller's

proposal. Any change to any law, rule, regulation, order, code, standard or

requirement which requires any change hereunder shall entitle Seller to an equitable

adjustment in the prices and any time of performance.
