The 500-FOD920 contactor is a 2-pole contactor. It belongs to the Bulletin 500 series from Allen-Bradley. The 500-FOD920 contactor is available in an open enclosure. The NEMA size of this contactor is size 5. The contactor includes one normally-open auxiliary contact. The coil on the contactor has a 110 Volts AC voltage rating at 50 Hertz frequency and a 120 Volts AC voltage rating at 60 Hertz frequency. The 500-FOD920 contactor is rated for about 5 million operations. The operating time specifications for the contactor include 18 milliseconds of average drop-out time and 25 milliseconds of average pick-up time. The recommended wire size for power terminals is AWG 4 to 500 MCM. The power contacts are made from silver alloy and the auxiliary contacts are made from pure silver. Wires rated for 75 degrees Celsius or higher must be sized according to the local electrical codes.

The 500-FOD920 contactor is designed for vertical mounting. The installation altitude for the contactor should not exceed 10,000 feet above sea level or the contactor will need to be derated. The ambient operating temperature range for the contactor is -25 to 65 degrees Celsius. Condensation should not be allowed to form on the 500-FOD920 contactor. The metal parts on the contactor are treated to resist corrosion. The 500-FOD920 contactor can be used with the J and R fuse types and it is rated for a maximum voltage 600 Volts AC. The available short circuit RMS symmetrical rating is 100,00 Amps. All the power connections are located on the top of the contactor for wiring convenience. The 500-FOD920 contactor can be wired for both single-phase and 3-phase applications. The contactor is available as a complete factory-assembled unit.
