HY 379229

Frequently Asked Questions

Q: What is the HY 379229 and what does it do in a Hyster electric lift truck?
A: The HY 379229 is a genuine OEM fixed contact for Hyster electric lift trucks. Fixed contacts are stationary electrical components used in contactor assemblies to create and maintain a stable current path during electrical operations. They work with moving contacts to open and close power circuits in the lift trucks electrical control system.

Q: Which Hyster electric lift truck models use the HY 379229 fixed contact?
A: This contact is designed for Hyster material handling equipment requiring robust electrical contact assemblies. The HY 379229 is compatible with various Hyster electric lift truck models and electrical contactor assemblies. Verify your equipment serial number and contactor model to confirm fitment before ordering.

Q: What material is the HY 379229 fixed contact made from?
A: Hyster OEM fixed contacts like the HY 379229 are typically manufactured from silver alloy or similar conductive materials to ensure stable current paths and resistance to arcing and oxidation. This material composition provides durability and reliability in electrical contactor applications.

Q: What symptoms indicate the HY 379229 fixed contact needs replacement?
A: Signs of contact wear or failure include intermittent power loss during operation, difficulty engaging the contactor, visible arcing or pitting on the contact surface, or continuity testing that shows high resistance. If the contactor clicks but does not fully energize the lift mechanism, the fixed contact may be defective.

Q: How does the HY 379229 differ from moving contacts in a contactor assembly?
A: Fixed contacts remain stationary in the contactor housing and serve as one half of the contact pair. Moving contacts are attached to an armature that opens and closes against the fixed contacts to complete or break the circuit. Both must be in good condition for proper contactor operation.
