Frequently Asked Questions
Q: What is a stationary contact tip and how does it differ from moving contacts?
A: A stationary contact tip is the fixed contact surface mounted to the contactor frame. It pairs with a moving contact that bridges the gap when the contactor coil energizes. Stationary tips experience arcing and erosion on one side only, while moving contacts wear on both surfaces. Both must be replaced when pitting exceeds manufacturer tolerances.
Q: Which lift truck brands use the PR 201276 stationary contact tip?
A: PR 201276 is compatible with GE-manufactured contactors found in Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich electric lift trucks. Cross-reference your contactor base part number to confirm compatibility before purchasing.
Q: What are the material specifications for PR 201276?
A: PR 201276 is constructed from silver-cadmium alloy with a rated contact pressure of 150A at 24VDC. The contact face is precision-machined to ensure parallel alignment with the moving contact, which is critical for reliable arc suppression and current distribution.
Q: How do I diagnose if the stationary contact tip is worn or damaged?
A: Inspect the contact surface with a magnifying glass or flashlight. Worn tips show black pitting, erosion craters, or transfer buildup on the contact face. Test continuity across the contact with a multimeter when the contactor is de-energized. If resistance exceeds 0.1 ohms or continuity is intermittent, the stationary tip must be replaced.
Q: How often should stationary contact tips be replaced?
A: Stationary contact tips typically require replacement every 3,000 to 5,000 operating hours in standard warehouse service. High-frequency use, wet-floor operations, and cold-storage environments accelerate wear and may require replacement every 1,500 to 2,500 hours. Replace both stationary and moving tips together for balanced arc performance.
