Frequently Asked Questions
Q: What is the CR 118396 contactor and how does it differ from the CR 118281-1?
A: The CR 118396 is a contactor used in Crown electric lift truck control circuits. It differs from the CR 118281-1 in amperage rating, voltage specification, or application. The CR 118396 is used for different motor circuits or in trucks with different power requirements. Always verify the correct contactor part number for your trucks control module and motor configuration.
Q: Is the CR 118396 a 24-volt or 48-volt contactor?
A: Verify your trucks electrical system voltage before ordering. Check the main battery pack label on your truck and the control module documentation. Installing the wrong voltage contactor will damage the control circuit and prevent the truck from operating. Contact your truck documentation or control module to confirm the correct voltage specification.
Q: What is the amperage rating of the CR 118396?
A: The CR 118396 is rated for a specific continuous amperage load based on the motor circuit it controls. Do not exceed the rated amperage or the contactor will overheat and fail. Refer to your trucks control module documentation or motor specifications to confirm the amperage requirement matches the CR 118396 rating.
Q: What are the common failure modes for the CR 118396?
A: Common contactor failures include burned or pitted contact surfaces from arcing, corrosion of the coil windings from moisture exposure, mechanical wear of the plunger mechanism, or electrical failure of the control coil. Over-current events or thermal cycling also degrade contactors. Failed contactors result in drive loss, intermittent operation, or control circuit faults.
Q: How do I diagnose a failed CR 118396 contactor?
A: Test the contactor by applying the correct control voltage to the coil terminals and listening for a click sound and feeling for mechanical movement of the plunger. If the coil does not energize or the plunger does not move, the contactor is failed. Use a multimeter to check for resistance across the main contacts. Open or high-resistance contacts indicate failure.
Q: Are there cross-reference part numbers for the CR 118396?
A: The CR 118396 is a Crown OEM part number. Cross-references may exist from other manufacturers, but compatibility depends on exact coil voltage, amperage rating, contact configuration, and physical mounting. The OEM contactor is the safest choice. If considering alternatives, verify electrical specifications and mechanical fitment carefully against your trucks control module and motor circuit.
