Frequently Asked Questions
Q: What is the amperage rating and application of the PR 201278 GE contactor?
A: PR 201278 is a GE-manufactured contactor rated at 150A, designed for 24VDC lift truck circuits. It controls motor power in electric pallet jacks and lift trucks, switching the motor on and off in response to solenoid energization. This rating handles standard Crown, Toyota, and Raymond electric lift truck motors without overheating.
Q: Which lift truck models and brands use the PR 201278 150A GE contactor?
A: PR 201278 is found in Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich electric lift trucks rated 3,000 to 6,000 pounds. Cross-reference the contactor base part number on your equipment to confirm compatibility. Some models may have been retrofit with equivalent contactors, so verify electrical specifications match before ordering.
Q: What are the electrical specifications and coil voltage for PR 201278?
A: PR 201278 operates at 24VDC with a control circuit coil voltage of 24VDC. Contact load rating is 150A at 24VDC. The contactor has normally-open main contacts and includes overload protection integration in most lift truck applications. Verify your battery voltage is 24V before installation to prevent coil damage.
Q: What failure symptoms indicate a PR 201278 contactor needs replacement?
A: Failed contactors show these symptoms: motor does not engage when drive control is pressed, coil hums but contacts do not close, clicking sounds from the contactor area, intermittent motor power loss, or visible burning and pitting on contact surfaces. Test coil continuity and contact resistance with a multimeter to confirm failure.
Q: What is the typical lifespan of a 150A GE contactor in lift truck service?
A: A 150A GE contactor like PR 201278 typically lasts 5,000 to 10,000 operating hours in standard warehouse service. Contactors in wet or corrosive environments may fail sooner due to contact pitting and coil insulation breakdown. High-frequency switching, overload conditions, and battery voltage fluctuations accelerate wear. Monitor contact resistance annually and replace when resistance exceeds 0.15 ohms.
