The Allen-Bradley 500-BOH92 contactor is a Bulletin 500 contactor. The NEMA size of the contactor is 1 and it is available without an enclosure. The nominal coil voltage for the 500-BOH92 contactor is 200 to 208 Volts AC at 60 Hertz. The continuous current rating for the 500-BOH92 contactor is 27 Amps. When used with 3-phase input voltage, the contactor is rated for a maximum of 7.5 Horsepower at 200 Volts AC. The contactor must be mounted in a vertical orientation. The recommended operating temperature range for the 500-BOH92 contactor is -25 to 65 degrees Celsius, provided that condensation on the contactor is prevented. The maximum recommended installation altitude for the 500-BOH92 contactor is 10,000 feet, and beyond this limit, the output of the contact will derate. The metal parts on the 500-BOH92 contactor are treated to prevent corrosion.

The wire size recommended for the power terminals on the Allen-Bradley series 500 500-BOH92 contactor is AWG 14 to AWG 8. The required torque on power terminal wire clamps and pressure connectors or lugs is 20 pounds on an inch. The rated mechanical life of the contactor is 10 million operations. The pick-up time is 21 milliseconds on average and the drop-out time is 16 milliseconds on average. To prevent equipment damage and injury to the operators, the 500-BOH92 contactor should only be installed by trained and experienced technicians. Note that electrical shocks can occur if the 500-BOH92 contactor is installed or is replaced while the system power is connected. Therefore, Allen-Bradley strongly recommends disconnecting the main supply before any work involving the 500-BOH92 contactor is performed.
