Product Description
Silver-cadmium contact tips designed for high-amperage electric lift truck contactors. These direct replacement contact tips provide superior arc resistance and electrical conductivity for reliable motor engagement. Engineered for Crown, Toyota, Raymond, and Yale electric pallet jacks and forklifts, they deliver consistent performance under frequent switching cycles and warehouse operating conditions.
Frequently Asked Questions
Q: What are contact tips used for in electric lift equipment?
A: Contact tips are conductive components in contactors that complete electrical circuits during contactor operation. They carry high-amperage current and are subject to arcing and erosion. When contact tips wear, electrical continuity degrades and the contactor fails to energize the lift motor reliably.
Q: How do I know if contact tips need replacement?
A: Worn contact tips show these symptoms: motor does not engage smoothly, coil hums but motor does not turn, intermittent power loss, visible pitting or discoloration on the contact surfaces when visually inspected, or resistance increases during continuity testing. Replacement is required when surfaces are visibly eroded or test continuity fails.
Q: What material are PR 201273 contact tips made from?
A: PR 201273 contact tips are manufactured from silver-cadmium alloy, which provides superior arc resistance and electrical conductivity for high-amperage applications common in lift truck contactors. This composition extends lifespan under frequent switching cycles.
Q: Which contactor models does PR 201273 fit?
A: PR 201273 is compatible with GE and Siemens contactors used in Crown, Toyota, Raymond, and Yale electric lift trucks. Verify contactor part number and amperage rating (typically 150A to 200A) before ordering to ensure fitment.
Q: What is the typical lifespan of contact tips?
A: Contact tip lifespan depends on switching frequency and load. In typical warehouse service, tips last 3,000 to 5,000 operating hours before visible erosion requires replacement. Cold-storage and wet-environment applications may shorten lifespan due to moisture and temperature stress on the silver-cadmium bond.
