Frequently Asked Questions
Q: What is the WM 20-7301781 contact used for?
A: The WM 20-7301781 is an electrical contact used in contactor, relay, or motor control assemblies on electric lift trucks. It completes or breaks electrical circuits to control motor operation, solenoid valves, or charging systems.
Q: Which lift truck systems use the WM 20-7301781 contact?
A: This contact is used in electric lift truck models from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. It may be found in motor contactors, control relays, or battery charging circuits. Verify your equipment model and electrical schematic before ordering.
Q: What material is the WM 20-7301781 contact made from?
A: Electrical contacts are typically made from silver alloy, copper alloy, or composite materials designed to resist arc erosion and oxidation. The exact material depends on the contact rating and intended application. Consult product specifications for material composition.
Q: What are signs that the WM 20-7301781 contact is worn and needs replacement?
A: Worn contacts cause intermittent electrical faults: motor does not start reliably, charging circuit operates intermittently, solenoid valve sticks or fails to energize, or visible arcing/pitting on the contact surface. Replace contacts when corrosion or pitting appears.
Q: What is the current rating for the WM 20-7301781 contact?
A: Verify the amperage and voltage rating from your truck manual or the contactor/relay nameplate. Using an undersized contact can cause overheating and failure. Using an oversized contact will not damage the truck but may not mount correctly.
