Frequently Asked Questions
Q: What is the BR 39187-001 contactor used for?
A: The BR 39187-001 is an EV-100 F&R (forward and reverse) contactor rated at 150A continuous for directional motor control in Barrett electric lift trucks. It is a 24VDC DPDT (double-pole double-throw) contactor with panel mount configuration.
Q: What are the technical specifications for the BR 39187-001?
A: Nominal coil voltage is 24VDC with 150A continuous current rating. The contactor features silver alloy contacts with 0.290 inch tip size and insulated phenolic housing. Mounting is panel mount configuration for EV-100 systems. Cross-reference part numbers are BR39187-001, BR39187001, and 39187001.
Q: What Barrett models is the BR 39187-001 compatible with?
A: The BR 39187-001 is designed for Barrett WRPN 60/80 electric pallet jacks equipped with EV-100 control systems. Confirm your truck model and control system match EV-100 specifications before ordering.
Q: What do the silver alloy contacts do?
A: Silver alloy contacts provide reliable electrical continuity and arc suppression during motor direction switching. They maintain low contact resistance under repeated forward and reverse cycling, which is essential for directional control in pallet jacks.
Q: How do I identify if the BR 39187-001 is failing?
A: Signs of contactor failure include: the truck does not respond to forward or reverse control, intermittent directional control, audible clicking when engaging controls, or visible burned or pitted contact surfaces. Replace the contactor if any of these symptoms occur.
Q: Can the BR 39187-001 be repaired or does it need replacement?
A: Contactors are sealed assemblies and are not field-repairable. Once contacts deteriorate or the coil fails, the entire unit must be replaced. Do not attempt to clean or refurbish internal contact surfaces.
