Frequently Asked Questions
Q: What is a contact tip in electrical systems?
A: A contact tip is the wearing part that makes and breaks electrical connections in contactors, relays, and motor controllers. It conducts current under load and is subject to arcing and erosion.
Q: Why do contact tips wear out?
A: Contact tips wear from electrical arcing, thermal cycling, and mechanical friction. Over time they develop pitting and erosion, reducing conductivity and causing voltage drop.
Q: What are the signs of a failing contact tip?
A: Failing contact tips cause intermittent power loss, slow response time, clicking or chatter when energizing circuits, and visible burning or discoloration in the control cabinet.
Q: Is BA 111220 compatible with different lift truck electrical systems?
A: Contact tip compatibility depends on the specific contactor model and electrical configuration. Verify the part fits your contactor assembly and voltage rating before ordering.
