Product Description
Stationary Contact Tip Assembly for GE electric lift truck contactors. The PR 201277 provides the fixed contact surface in contactor assemblies, enabling reliable motor engagement and power distribution in electric pallet jacks, reach trucks, and order pickers. Manufactured from silver-cadmium alloy, this contact tip resists arc pitting and electrical erosion during high-frequency switching cycles typical in warehouse and dock operations. Rated for 150A and above, the PR 201277 ensures consistent electrical continuity and extends contactor service life when maintained as part of a complete contact assembly. Direct replacement for worn or damaged stationary tips in Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich electric lift equipment.

Frequently Asked Questions
Q: What is the function of a stationary contact tip in a contactor assembly?
A: The stationary contact tip provides the fixed contact surface for the contactor. When the coil energizes, the moving contact arm bridges to the stationary tip, completing the circuit and supplying power to the lift motor. The stationary tip is mounted rigidly to prevent vibration-induced separation and loss of contact.
Q: Which contactor bases and lift truck models use PR 201277?
A: PR 201277 fits GE contactors rated 150A and above, commonly found in Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich electric lift trucks built from 2000 onward. Verify your contactor part number and amperage rating on the manufacturer label before ordering.
Q: What material composition ensures PR 201277 reliability?
A: PR 201277 is composed of silver-cadmium alloy, chosen for its excellent arc resistance and electrical conductivity. The alloy maintains contact integrity under high-amperage switching, resisting pitting and surface erosion common in electric lift truck service where the contactor switches load hundreds of times per shift.
Q: What symptoms indicate a worn PR 201277 stationary contact tip?
A: Worn stationary tips cause motor engagement delays, coil humming without motor rotation, intermittent loss of drive power, or visible black pitting on the contact surface. A failed stationary tip will show complete loss of continuity when tested with a multimeter or cause the contactor to chatter and vibrate during operation.
Q: What is the expected service life of PR 201277 contact tips?
A: Under standard warehouse conditions, PR 201277 contact tips last 3,000 to 5,000 operating hours. Extended use in wet floors, cold storage, or high-frequency switching zones may reduce lifespan to 1,500 to 2,500 hours. Always replace stationary and moving tips as a pair to ensure balanced contact pressure and arc suppression.
