MAIN CONTACTOR
Frequently Asked Questions
Q: What is the BA 127568 main contactor and how does it work?
A: The BA 127568 is a main contactor used in electric lift truck and powered pallet jack electrical systems. It acts as a heavy-duty electrical switch that connects or disconnects the 24VDC battery from the pump motor circuit. When the operator engages the lift or lower control, the contactor closes to allow current to flow to the pump, enabling hydraulic lift operation. It is a critical safety and control device.
Q: What are the current and voltage ratings for the BA 127568?
A: The BA 127568 is rated for continuous duty operation in 24VDC electrical systems typical of Baker and equivalent lift trucks. The exact amperage rating and solenoid coil voltage are engineered for the pump motor current draw and truck electrical architecture. Contact us with your equipment make, model, and serial range to confirm the correct BA 127568 specification for your application.
Q: How does the BA 127568 differ from other contactors?
A: The main contactor designation indicates this device handles the primary motor circuit load. It differs from auxiliary contactors or relays, which control lower-current circuits or valve solenoids. The BA 127568 must withstand high continuous current and frequent switching without failure. Its robust design and rating distinguish it from smaller general-purpose contactors.
Q: What failure symptoms indicate the BA 127568 needs replacement?
A: Common failure signs include the pump not running when the control lever is engaged, a loud buzzing or humming from the contactor without pump motor start, inability to reach full pump speed, or intermittent operation that improves when the contactor is tapped. Burned or pitted main contacts cause these symptoms. If the solenoid coil is burned out, you will smell burning insulation. Replace the contactor immediately.
Q: Which lift trucks use the BA 127568 main contactor?
A: The BA 127568 is engineered for Baker electric lift trucks and compatible material handling equipment. It also fits Crown, Toyota, Raymond, Yale, Hyster, and other OEM lift trucks with matching 24VDC electrical systems and motor current requirements. Always verify your truck electrical schematic and contactor specifications before purchasing. Using an incorrect contactor rating risks electrical failure and equipment damage.
