Allen-Bradley 500FL-AOD92 Industrial Contactor

Allen-Bradley 500FL-AOD92 is a two-pole, NEMA Size 0 feed-through lighting contactor designed for electrically held, non-motor lighting loads. With an open enclosure and a 115–120 V AC, 60 Hz coil, it can switch up to 20 A for lighting, ballast, and related loads, while delivering a continuous current rating of 18 A and a service limit of 21 A. The unit uses silver alloy power contacts and silver auxiliary contacts (up to eight auxiliary contacts max), and it supports through-wiring for feeder-disconnect applications. Its compact footprint measures about 90.5 mm wide by 152 mm high by 113 mm deep, and uses #14 to #10 AWG conductors on power terminals, with a torque specification of 20 in-lb. The coil burden is 29 VA at 60 Hz, and heat dissipation is 5.9 W, reflecting efficient operation for lighting controls. Mechanical life is listed at about 10 million operations, with typical pull-in around 21 ms and drop-out around 16 ms. This 500FL contactor is positioned for 2-pole configuration in open-type, feed-through installations, where reliable, quick-switching control of lighting or other non-motor loads is required, and where a through-wiring design can simplify field wiring in commercial or industrial electrical panels.
