Electricity is an inseparable part of our daily lifestyle. In residential, commercial and industrial sectors there are myriad systems, equipments and sophisticated appliances that depend on electrical energy. Uncontrolled electrical power can be extremely dangerous. Overloads, crowded wiring, short-circuits and all kinds of interruptions in electric supply can lead to devastating losses, least of them being financial.

We at STANDARD are proud to be known and respected the world over for our range of superior quality electrical control and safety devices. Through these, we speak of our lasting concern for safety, economy and productivity for our customers.

The latest product from STANDARD is 10kA MCB, is an advanced Indian design of high performance, current limiting and switching for control and protection of industrial, commercial & domestic electrical sub circuits. It meets the latest specification IS / IEC : 60898-1 of B & C Characteristics.

The primary function of the MCB is to protect the installation such as cable & other components from damage, resulting due to overload & short-circuit fault. Under overload heating effect can occur on cable. Protection in this respect is assured by matching the cable rating to the current rating of MCB.

Under short-circuit condition, mechanical damage can occur due to strong magnetic field caused by high current peaks and overheating of cables on account of "exclusive let through energy". The current limiting action of "MCB" ensures low value of both peak current "cut off" and minimum let through energy.

TIME CURRENT CHARACTERISTIC CURVES

Based on the Tripping Characteristics, Standard MCBs are available in ‘B’, ‘C’ and ‘D’ curve to suit different types of applications.

‘B’ Curve: for protection of electrical circuits with equipment that does not cause surge current (lighting and distribution circuits).

Short circuit release is set to (3 - 5) In

‘C’ Curve: for protection of electrical circuits with equipment that causes surge current (inductive loads and motor circuits).


‘D’ Curve: for protection of electrical circuits which causes high inrush current, typically 12-15 times the thermal rated current (transformers, X-ray machines etc.)


CURRENT LIMITING DESIGN

In a current limiting breaker, the tripping & arc control mechanism is so designed that under short circuit conditions, the contacts are physically separated and the electrodynamic forces set up by fault current assist the extinction in less than half cycle.

The figure shows the current limiting effect of a circuit breakers. Fault Traces for Voltage & Current

0 = Point of fault initiation

tx = Contact opening time (i.e., creation of arc)

t1 = Current / Voltage peak (i.e., current limitation)

t2 = Time to total extinction of arc (i.e., complete shutdown of fault current)

PROTECTION UNLIMITED

STANDARD MCBs protect against overload and short circuit.

Overload Protection It is achieved by thermal operation of the bimetal strip which deflects when heated by the over current going through it, thereby tripping the operating mechanism and causing the contact to open.

Thermostatic Bi-metal It is a composite material comprising of two metallic layers of different co-efficient of thermal expansion which are permanently bonded together by pressure welding.

Short Circuit Protection In short circuit, the high current in the range of kA energises the solenoid and a magnetic field is created. Due to this magnetic field the anchor is pulled down which pushes the plunger to strike the inner latch, causing instantaneous opening of the contacts.

The flow of current through electrical facilities always involves risks. Poorly insulated equipment, faulty wires and incorrect use of an electrical device cause currents to flow through the wrong path (i.e. through the insulation) to the earth. This current is called ‘Leakage Current’.

Earth leakage is an electrical hazard and is responsible for electrical shocks and fire risk. Earth leakage and its associated hazard can be prevented by Residual Current Circuit Breaker (RCCB), also popularly known as Earth Leakage Circuit Breaker (ELCB).

Against Electrocution

The use of exposed, substandard, badly wired, wrongly connected or damaged equipment as well as frayed or badly repaired cables reduces the safety of an installation and increases the risk of person receiving an electric shock.

Electrocution is a passage of current through human body, which is dangerous. The flow of current through human body effects vital functions.

Effect of electric current through human body has been well researched and following chart summarizes the results.

However, electrocution should not be viewed in terms of “current” alone, but in terms of “contact voltage”. A person gets electrocuted by coming in contact with an object that has a different potential from his/her own. The difference in potential causes the current to flow through the body.

The human body has known limits:• Under normal dry conditions, voltage limit = 50V• In damp surroundings, voltage limit = 25V

EFFECT OF ELECTRIC CURRENT THROUGH HUMAN BODY

500 mA Immediate cardiac arrest resulting in death

70-100 mA Cardiac fibrillation; the heart begins to vibrate and no

20-30 mA Muscle contraction can cause respiratory paralysis

10 mA Muscle contraction : the person remains “stuck” to the conductor

1-10 mA Prickling sensations

AGAINST INDIRECT CONTACT

Over current protection devices like MCB are unable to act promptly on small earth leakage currents. To comply with wiring regula-tions, the earth fault loop impedance in Ohms, multiplied by the rated tripping current of the RCD in amperes must not exceed 50.

Example

For an RCD with a rated tripping current of 30mA, the maximum permissible earth fault loop impedance is calculated as follows: Zs (max) = 50 / In = 50/0.03 = 1,666

AGAINST FIRE

The majority of fires which occur as a result of faulty wiring are started by current flowing to earth. Fire can be started by fault current of less than 1 amp.The normal domestic overload protective device such as a fuse or MCB will not detect such a small current. A correctly chosen RCD will detect this fault current and interrupt the supply, hence, reducing the risk of a fire starting.

WORKING PRINCIPLE

The RCCB works on the current balance principle. The supply conductors, i.e. the phases and the neutral, are passed through a torroid and form the primary windings of a current transformer. Its secondary winding is connected to a highly sensitive electromagnetic trip relay, which operates the trip mechanism.

In a healthy circuit, sum of the currents in phases, is equal to the current in the neutral and the vector sum of all currents is equal to zero. If there is any insulation fault in the current and leakage current flows to earth, the currents do not balance and their vector sum is not equal to zero. This imbalance is detected by the core balanced current transformer, the RCCB is tripped and supply to load is interrupted. The trip mechanism is operated at a residual current between 50-100% of its rated tripping current.

SELECTION

30 mA : A 30 mA ELCB will provide a high degree of protection against electrocution in an accidental shock hazard situation. The current flowing through human body could be between 80mA and 240mA depending on the resistance of the human body and the voltage across it.

Zone : Physiological Effects

Zone 1 : Usually no reactions

Zone 2 : Usually no harmful physiological effects

Zone 3 : Usually no organic damage to be expected. Likelihood of muscular contraction and difficulty in breathing, reversible disturbances of formation and conduction of impulse in the heart and transient cardiac arrest without ventricular fibrillation increases with current magnitude and time.

Zone 4 : In addition to the effects of Zone 3, probability if ventricular fabriliation increased upto 5% (curve C2) upto 50% (curve C3) and above 50% beyond curve C3. It increases with magnitude and time, and pathophysiological effects such as cardiac arrest, breathing arrest and heavy burns may occur.

To be within zone of the IEC curve as shown above. It is necessary for the ELCB to operate within 50ms at 240 mA and 150ms at 80mA. Both these conditions are satisfied by 30mA ELCB.

For households, individual outlets, wet areas and temporary installations, ELCB with sensitivity not exceeding 30mA is advisable.

100 mA : A 100mA ELCB will normally give high degree of protection against electrocution but there is a possibility that the shock current could fall below the tripping level of ELCB. This could occur if additional resistances to that of human body are included in the earth path.

The 100mA RCCB protects against leakage currents and indirect contact with earth loop impedance upto 500 Ohms.

300 / 500mA : A 300/500 mA ELCB may be used where only fire protection is required. eg., on lighting circuits, where the risk of electric shock is small. 300/500mA ELCB will not give any protection against electrocution.

RCBO

29

Standard New RCBO is a single composite device which provides protection against over currents and earth leakage faults in the same width and profile as that of a standard MCB. It is designed for use in domestic, commercial and industrial distribution sys-tems at the most downstream circuit for ensuring high degree of protection to the user for a particular circuit. In normal use, it is safe to use and free of to user as well as to environment.

Features

• Pulsating dc protection - Type A• Discrimination using time delay - Type S RCBO• Controlled response VD RCBO (Electronic)• Protection in case of loss of supply neutral in SPN RCBO only• Enhanced immunity to nuisance tripping• Positive contact indication: Red for ON , Green for OFF• Short circuit breaking capacity 10 kA.• Large terminal capacity: RCBOs have 35 mm2 for cool running

while in operation.• Protection in case of loss of supply neutral: Even in event of

loss of supply neutral, Standard RCBO provides protection against earth faults . The Functional Earth (FE) white color wire connected to earth provides this protection.

• Controlled response & immunity to nuisance tripping: The trip level and the response time of the Standard VD (Voltage Dependent) RCBO using electronic circuit is set to very precise values and thereby provide greater immunity to nuisance tripping that can be caused by mains borne noise, surge voltages, lighting surges, reactive loads, mains filters, etc.

• Neutral to earth faults: A connection that occurs between N and E on the load side of any RCBO will impact on its performance and cause the trip level to increase. In the case of a N - E fault, the user may have no way of knowing that this fault exists and that the RCBO has been desensitised. Under this condition, the Standard VD RCBO provides a far greater level of protection than a normal VI (Voltage Independent) RCBO.

Aesthetics & Convenience

• The new module’s unique compact construction enables far more devices to be fitted into a distribution board than previously possible, and 2 Module RCBO can simply replace existing MCB 2 pole when upgrading a board.

• High stacking density = smaller chasis & distribution boards.

Reliability & continuity of service

• Enhanced discrimination with Standard MCBs• Back up to 10 kA with BS & DIN fuses• Retrofits Standard MCBs in distribution boards with no

modifications in general• Robust construction.

Energy limiting

Standard RCBO meets the requirements for energy let through by IEC & British Standard for energy limiting class 3.

Features & Benefits

30

ADDITIONAL RANGE - TYPE A & S

Type A - Pulsating DC Protection: Any electrical appliance with power control has the ability to produce earth fault currents with pulsating DC (rectified AC) components. RCBOs that provide this type of protection are referred to as Type A RCBOs.

VI RCBOs do not provide this protection, and are referred to as Type AC RCBOs. Standard VD RCBOs have been specifically designed to provide protection against pulsating DC fault currents.

• Type S- Selective or Time Delay: RCBOs are also divided into two categories determined by their response time to an earth fault current, as follows

• General Type - having a trip time<300mS for fault currents of IDN and < 40ms for fault currents > 5 IDN.

• S Type- having a trip time of 150 - 500mS for IDN, and 40 - 130mS for >5 IDN.

(IDn is the rated residual operating current of the RCBO)

As the name implies, general types are intended for general purpose use. However, S (selective) types are normally used in conjunction with downstream general type RCBOs.

The S type effectively provides discrimination in terms of the response time to earth fault currents for upstream and downstream RCBOs. For example, when two RCBOs are connected in series the first RCBO will often be an S type.

IP RATINGSThe IP (International Protection) rating given to an enclosure states the degree of protection it offers by means of two digits. A summary of these is shown below, for a more detaileddefition, see IEC 529 : 1989, BS EN 60529 : 1992.

FIRST DIGIT Protection against solid foreign objects and access to hazardous parts.The first digit covers protection against penetration by solid objects, which includes hands and tools such as screwdrivers. At the lowest of seven levels, 0, no protection is offered, either of the equipment itself from damage by intrusion or of a person contacting live or moving parts. At the highest, there shall be no entry of dust.

SECOND DIGIT Protection against ingress of water. The second digit covers the degree of protection against the entry of water, on a progressive scale. for example, number 1 indicates that dripping water shall have no harmful effect, and number 6, that water projected in powerfuljets against the enclosure from any direction shall have no harmful effects.

The letter X can be used in place of the first or second digit to indicate that tests have either not been made or are not applicable.

Protected against strong jets of water e.g. for use on ship decks -limited ingress permitted

Protected against low pressure jets of water from all directions -limited ingress permitted

Protected against after splashed from all directions -limited ingress permitted

Protected against sprays of water up to 60° from the vertical

Protected against direct sprays of water up to 15° from the vertical

Protected against vertically falling drops of water eg. condensation

CATEGORY OF DUTY

The category of duty defines the basic type of circuit and switching capability of the device, and selection should be made accordingly.

Utilisation Category Typical Applications

AC20/DC20 Connecting and disconnecting under no-load.

Assumes all switching operations are carried out by other capable devices before this device is operated.

AC21/DC21 Switching of resistive loads including moderate overloads.

Suitable for purely resistive type loads devices can switch 150% of its rated current under fault conditions

Ue = Rated Operational Voltage

The normal line-to-line voltage of the

system should not exceed (Ue)

Ui = Rated Insulation Voltage

The voltage on which the dielectric properties have conventionally been based using tests at high voltage and mains frequency. It is intended to replace this value with (Uimp)

Uimp = The voltage on which clearance distances are based.

The value of transient peak voltage the circuit breaker can withstand from switching surges or lighting strikes imposed on the supply.

e.g. Uimp = 8kV, Tested @8kV peak with

1.2/50m (ms)S impulse wave

In = Rated Current

The current which the circuit breaker will carry continuously under specified conditions and on which the time / current characteristics are based.

Unless otherwise slated (In) is based on a reference ambient temperature of 30° centigrade.

Icu Rated Ultimate Short Circuit

Breaking Capacity

The calculated prospective fault current at the incoming terminals of the circuit breaker should not exceed (Icu).

Exception: Using back-up protection as specified by the manufacturer.

Ics Rated Short-time Withstand Current

The maximum level of fault current operation after which further service is assured without loss of performance.

Icw Rated Short-time Withstand Current

Circuit breakers of utilisation category ‘B’ have a short-time delay allowing time-graded selectivity between circuit breakers in series.

(Icw) is the current the circuit breaker will withstand for the maximum short-time delay time. Preferred times are 0.05, 0.1, 0.25, 0.5 and 1.0 second.

Ui = 660V

Tested@

2500V ac 50Hz

AC22/DC22 Switching of mixed resistive / inductive loads, including moderate overloads.

Suitable for mixed resistive / inductive loads. Devices can switch 300% of its rated current under fault conditions.

AC23/DC23 Switching of highly inductive loads. Devices complying with AC23/DC23 are

provided mainly as back-up to other means of switching. e.g. contacts. In the event of failure of functional devices, an AC23 / DC23 type device can safety interrupt a stalled motor current. Where devices are the only means of controlling individual motors, they should comply with the requirements of appendix A of the standard. (IEC 60947-3)
