Frequently Asked Questions
Q: What are the electrical specifications of the 5051755-03 contactor?
A: The 5051755-03 is a 24VDC single pole, single throw (SPST) contactor rated for 180A continuous current at 24VDC. It features Class B coil insulation for reliable operation in industrial electric lift truck control circuits.
Q: Which equipment models is the 5051755-03 compatible with?
A: The 5051755-03 is designed for 24VDC electric lift truck systems from Crown, Toyota, Raymond, Yale, Hyster, and other industrial manufacturers. Verify voltage compatibility with your equipment before ordering, as improper voltage will damage the contactor and control circuit.
Q: What are the cross-reference part numbers for 5051755-03?
A: Cross-reference part numbers include CTR-24-251, 7001647, CTR-24-239, 800076733, CTR-12-127, and 8730877. Confirm the correct cross-reference for your specific equipment model and serial range before ordering.
Q: Does the 5051755-03 have silver contacts, and why does that matter?
A: Yes, the 5051755-03 features silver contacts that provide low contact resistance and reliable high-current switching. Silver contacts resist oxidation better than copper, extending contactor life in industrial duty cycles common to electric lift trucks.
Q: Can the 5051755-03 be used as a direct replacement for the CTR-24-251?
A: Yes, the 5051755-03 supersedes and directly replaces the CTR-24-251. Both units share identical 24VDC coil voltage and 180A continuous current rating. Verify mounting dimensions and terminal configuration match your circuit board layout before installation.
Q: How should the 5051755-03 be maintained or inspected?
A: Inspect the contactor periodically for contact pitting, arcing, or discoloration. Verify coil voltage remains at 24VDC. Clean terminals to ensure secure connections. Replace if contacts show significant wear or if the contactor fails to energize or de-energize under normal circuit load.
