The mechanically held operation ensures that the contactor will not switch to during control power failure. It also ensures the removal of coil from the circuit for noise-free operation and the elimination of all coil losses after the contactor is latched. The control module microprocessor validates the control signal before operation, so it will not respond to momentary voltage spikes of noise. The operation command has a built-in. sec delay to avoid multiple short-term commands that can cause contact fatigue or failure. Also, the feedback loop prevents the contactor from getting out of sequence with switches, even after power failures. Application Description The mechanically held lighting contactor provides effective control in applications such as office buildings, industrial plants, hospitals, stadiums, airports, etc. They are ideal for applications that require quiet, energy-efficient operation. Designed to handle different load types: Tungsten (incandescent filament) Ballast (fluorescent and mercury arc) High intensity discharge (HID) Non-motor A resistive Single- and Three-Phase Motor Ratings position indication when button protrudes, contact is closed Power poles are available as single or double poles, creating different circuit combinations onvenient side access for field power wiring configuration indicator Robust pole terminals accept up to two AWG wires Figure -. NM Features Fast, sure three-point mounting Features See Figure -. amp power pole rating Up to poles maximum Power poles latch easily onto the base, and designating them as NO or N is a simple matter of left or right positioning. Additional poles, either NO or N, may be easily added at any time. Low magnetic noise results in quiet operation Low input VA permits long wire runs ome in a wide range of input voltages and with coils from V to V A and V to V D. Enclosed contacts resist contaminants for greater reliability ommon easily-installed power poles change from NO to N (or vise versa) simply by unlatching and rotating Power poles rated for a range of tasks: A rated contacts A motor rated Pilot duty rated contacts, rated A, are suitable for use on low level circuits down to V, ma Finger and back-of-hand safe power terminals Plug-in auxiliary contacts are N when installed on the right side of the base, NO on the left AE

2 February Operation -wire control is the choice for use with momentary devices allowing operation from multiple locations. A momentary pulse of energy operates the contactor while a second pulse on an alternate leg returns the contactor to its original state. -wire control is the choice for single output automatic operation or for operation from single-pole devices. When voltage is applied to the input terminals the contactor is latched into position (coil is removed from the circuit while control voltage is continuously supplied). When control voltage is removed, the latch is disengaged and the contactor is returned to its original state.
