® The service-limit current ratings represent the maximum rms current, in amperes, which the controller shall be permitted to carry for protracted periodsin normal service. At service-limit current ratings, temperature rises shall be permitted to exceed those obtained by testing the controller at itscontinuous current rating. The current rating of overload relays or trip current of other motor protective devices used shall not exceed the service-limitcurrent rating of the controller.

NEMA Size 1 — Cat No. AN16BNOAB
Product DescriptionNon-reversingThree-phase, full voltage magneticstarters are most commonly used toswitch AC motor loads. Starters con-sist of a magnetically actuated switch(contactor) and an overload relayassembled together.
NEMA Size 1 — Cat. No. AN56DNOAB
ReversingThree-phase, full voltage magneticstarters are used primarily for revers-ing of 3-phase squirrel cage motors.They consist of two contactors and asingle overload relay assembledtogether. The contactors are mechani-cally and electrically interlocked toprevent line shorts and energizationof both contactors simultaneously.
Features• Bimetallic Ambient Compensated
Overload relays — available in threebasic sizes covering applications upto 900 hp — reducing number ofdifferent contactor/overload relaycombinations that have to bestocked.These overload relays feature:a Selectable Manual or Automatic
Reset operation.a Interchangeable heater packs
adjustable ±24% to match motorFLA and calibrated for 1.0 and1.15 service factors. Heater packsfor smaller overload relay willmount in larger overload relay —useful in derating applicationssuch as jogging.
a Load lugs built into relay base.a Single-phase protection, Class 20
or Class 10 trip time.a Overload trip indication.a Electrically isolated NO-NC con-
tacts (pull RESET button to test).
• Long life twin break, silver cadmiumoxide contacts — provide excellentconductivity and superior resistanceto welding and arc erosion. Gener-ously sized for low resistance andcool operation.
• Designed to 3,000,000 electricaloperations at maximum hp ratingsup through 25 hp at 600V.
• Steel mounting plate standard on allopen type starters.
• Wired for separate or commoncontrol.
Non-reversing• Holding circuit contact(s) supplied
as standard:U Sizes 00-3 have a NO auxiliary
contact block mounted on right-hand side (on Size 00, contactoccupies 4th power pole position— no increase in width).
a Sizes 4-5 have a NO contactblock mounted on left side.
Q Sizes 6-7 have a 2NO/2NCcontact block on top left.
a Size 8 has a NO/NC contact blockon top left back and a NO on topright back.
Reversing• Each contactor (Size 00 - 8)
supplied with one NO-NC sidemounted contact block as standard.NC contacts are wired as electricalinterlocks.

OperationThese DC coil kits have separate pick-up and seal windings. A special (sidemounted) early-break NCI auxiliarycontact is used to either disconnect thepick-up winding or insert the sealwinding in series with the pick-upwinding, depending on the frame sizeof the contactor. DC coil kits come intwo styles, a suffix 1 and a suffix 4. The1 suffix contains only the special (sidemounted) early break NCI auxiliarycontact. The 4 suffix contains a NOcontact in the same package as thespecial (side mounted) early-break NCIauxiliary contact.
Note: For NEMA Sizes 00 and 0 and IECSizes A - F, contactors may utilize either suf-fix 1 or 4 DC coil kits; starters may utilize suf-fix 4 DC coil kits only. For NEMA Sizes 1 and2 and IEC Sizes G - K, both contactors andstarters may utilize a suffix 4 DC coil kit only.
On the above sizes only, when thespecial auxiliary package is mountedon the side of a contactor or starter,no standard auxiliary contact may bemounted on the same side.
Note: For NEMA Sizes 3 - 5 and IEC SizesL - S, special coil NCI clearing contact is anadd-on auxiliary (must mount on a basemount auxiliary contact; normally a 1NO).This arrangement will normally account fortwo of the three contact positions on theside of each contactor or starter.

Coil Data Notes
P.U. = Pick-up time is the average time taken from closing of the coil circuit to main con-tact touch.
D.O. = Drop-out time is the average time taken from opening of the coil circuit to main con-tact separation.
Cold = Coil data with a cold coil.
Hot = Coil data with a hot coil.
All data is based on a standard con-tactor with no auxiliary devices and a 120V AC or 24V DC magnet coil. Coil data has a ±5% range depend-ing on the application, therefore specific data may vary.

Electrical Life — AC-3 and AC-4 Utilization Categories
Life Load Curves
Cutler-Hammer’s Freedom Series NEMA contactors have been designed and manufactured for superior life performance in any worldwide application. All testing has been based on requirements as found in NEMA and UL standards and conducted by Cutler-Hammer. Actual application life may vary depending on environmental condi-tions and application duty cycle.
Utilization Categories
AC-1 — Non-inductive or slightly inductive loads, such as resistance furnaces and heating.
AC-2 — Starting of slip-ring motors.
AC-3 — Squirrel cage motors; starting, switching off motors during running.
AC-4 — Squirrel cage motors; start-ing, plugging, inching or jogging.
NOTE: AC-3 tests are conducted at rated device currents and AC-4 tests are conducted at six times rated device currents. All tests have been run at 460V, 60 Hz.
Contactor Choice
■
Decide what utilization category your application is and choose the appropriate curve.
■
Locate the intersection of the life-load curve of the appropriate contactor with the applications operational current (Ie), as found on the horizontal axis.
■
Read the estimated contact life along the vertical axis in number of operational cycles.
