Frequently Asked Questions
Q: What is the contact BR 27789-043?
A: The BR 27789-043 is an electrical contact set used inside the BR 27789-042 contactor. It consists of movable and stationary contact elements that make and break the circuit connection to the lift motor.
Q: When should BR 27789-043 contacts be replaced?
A: Replace the contact set when you observe pitting, burning, or erosion on the contact surfaces, or when the contactor fails to make a consistent electrical connection. High-cycle lift operations may require contact replacement every 2 to 3 years.
Q: What lift trucks use BR 27789-043 contacts?
A: These contacts fit inside the BR 27789-042 contactor assembly used in Crown, Toyota, Raymond, Yale, and Hyster electric lift trucks. Verify that the contact set matches your contactor amperage and voltage rating.
Q: What material are BR 27789-043 contacts made from?
A: The contact elements are typically manufactured from silver alloy or copper alloy materials that provide low electrical resistance and resistance to arcing and oxidation under repeated circuit switching.
