Frequently Asked Questions
Q: What is the NI 29348-L4005 contact tip and where is it used?
A: The NI 29348-L4005 is a contact tip component for Nissan electric lift truck contactor assemblies. It is a replaceable electrical contact element that makes and breaks the circuit to the drive motor. This part is typically used as a replacement within contactor rebuild kits or repair assemblies.
Q: What material is the NI 29348-L4005 contact tip made from?
A: The NI 29348-L4005 contact tip is constructed from silver-alloy contact material. This alloy provides high electrical conductivity and resistance to electrical arcing and oxidation during high-current switching cycles in 80V DC motor circuits.
Q: Can the NI 29348-L4005 be used as a standalone repair part or only in rebuild kits?
A: The NI 29348-L4005 is a component contact tip. It is sold individually or as part of contactor rebuild kits. If you are rebuilding a contactor assembly with functioning frame and coil, use this contact tip with matching contacts (such as the NI 29347-31K00) as a complete rebuild set. Consult the specific contactor assembly documentation to ensure correct component pairing.
Q: How long does the NI 29348-L4005 contact tip last before replacement?
A: Contact tips typically last 2-4 years or 3,000-5,000 switching cycles under normal duty. Heavy-duty or frequent start-stop operations reduce this lifespan. Contact wear is progressive, so gradual loss of power delivery or motor response indicates it is time to rebuild or replace the contactor.
Q: What is the difference between the NI 29348-L4005 and the NI 29347-31K00 contact?
A: Both are silver-alloy contact components used in Nissan contactors, but they serve different contact positions within the assembly. The NI 29348-L4005 is one type of contact tip, while the NI 29347-31K00 is the fixed contact element. Use both together when performing a full contactor rebuild to replace both moving and stationary contact surfaces.
