Frequently Asked Questions
Q: What is the BJ 1120-500005-00 contactor rated for?
A: The BJ 1120-500005-00 is a 24VDC main contactor with a 125A continuous current rating. It controls the primary power circuit in Big Joe PDS 20 and PDS 25 electric pallet trucks, switching the battery pack connection to the lift motor.
Q: Which Big Joe models use the BJ 1120-500005-00 contactor?
A: The BJ 1120-500005-00 is compatible with Big Joe PDS 20 and PDS 25 electric pallet trucks. Cross-reference part numbers include BJ1120-500005-00, BJ112050000500, and 112050000500.
Q: What materials are used in the BJ 1120-500005-00 contactor construction?
A: The BJ 1120-500005-00 features a high-impact thermoplastic frame, electromagnetic coil actuated mechanism, and copper alloy contacts. The panel-mount design allows direct installation into control systems.
Q: What does it mean if the contactor chatters or clicks repeatedly?
A: Repetitive chattering indicates an intermittent power supply or weak coil spring. Check the 24VDC supply voltage and connections to the coil terminals. If voltage is stable and chattering persists, the contactor requires replacement.
Q: Can the BJ 1120-500005-00 contactor be repaired or cleaned?
A: The BJ 1120-500005-00 is a sealed assembly and is not field-serviceable. If contacts are worn, burned, or the coil fails to energize, the entire contactor must be replaced. Attempting to disassemble voids the part warranty.
