CONTACT KIT (100 AMP)
Frequently Asked Questions
Q: What is included in the 156MCHI contact kit?
A: The 156MCHI is a 100 ampere contact kit containing the electrical contacts needed for high-amperage motor control circuits. The kit includes replacement contacts that complete current paths in the lift motor, drive motor, or pump motor circuits. Verify your lift truck model requires a 100 amp rating before ordering.
Q: Which electric lift truck models use the 156MCHI 100 amp contact kit?
A: The 156MCHI contact kit is compatible with electric forklifts from Crown, Toyota, Raymond, Yale, Hyster, and similar OEM brands operating at 100 amp capacity. Confirm your equipment model and amperage rating match this specification.
Q: How do I know the 156MCHI contacts need replacement?
A: Replace contacts when the lift truck exhibits loss of power during acceleration, intermittent motor function, clicking relay sounds with no motor response, or visible scorching around the motor control area. These indicate contact arcing or erosion.
Q: What is the typical lifespan of a 156MCHI contact kit?
A: A 100 amp contact kit in normal warehouse duty typically lasts 24 to 36 months. Aggressive acceleration, frequent heavy loads, or high ambient temperatures shorten contact life. Routine inspection helps identify wear before sudden failure.
Q: Is the 156MCHI suitable for high-frequency switching applications?
A: The 156MCHI is rated for normal lift truck duty cycles. In applications with very frequent motor cycling or rapid acceleration pulses, contact erosion accelerates. Verify your duty cycle matches manufacturer specifications to ensure adequate contact lifespan.
