Frequently Asked Questions
Q: What does the CL 908248 contactor do?
A: The CL 908248 is a reverse contactor for Clark electric lift truck control circuits. This contactor switches the direction of motor current flow to reverse the truck movement. It works in conjunction with the main drive contactor and is controlled by the direction control switch on the operator handle or console.
Q: Which Clark electric lift trucks use the CL 908248 reverse contactor?
A: The CL 908248 is compatible with various Clark electric pallet jacks and electric hand jacks that require reversible motor control. Verify your truck model, voltage rating, and control circuit configuration before ordering. Check your equipment electrical schematic to confirm this contactor matches your main contactor amperage rating and voltage class.
Q: What voltage rating does the CL 908248 have?
A: Confirm the voltage rating of the CL 908248 by cross-referencing your Clark equipment documentation or your existing contactor. Clark electric trucks typically use 12V, 24V, or 36V DC control circuits. Using a contactor rated for incorrect voltage will cause failure to engage or coil burnout.
Q: What is the amperage rating of the CL 908248 contactor?
A: The CL 908248 amperage rating determines the maximum motor current it can safely switch. Typical ratings for reverse contactors range from 50A to 200A depending on motor size. Do not use an undersized contactor as it will overheat and weld shut. Verify your motor amperage rating matches the contactor specification.
Q: How do I diagnose a faulty CL 908248 reverse contactor?
A: Symptoms of a failed reverse contactor include no reverse operation (truck will not back up), grinding or welding sounds when trying to reverse, or loss of electrical continuity in the motor circuit. Check that the direction control switch sends proper signal to the contactor. If the truck moves forward but not backward, the reverse contactor is likely defective and should be replaced.
