Frequently Asked Questions
Q: What is the HY 349975 contactor used for?
A: The HY 349975 is a high-speed contactor that controls power delivery to the lift truck motor. Operating at 180 amperes continuous duty with 12VDC coil voltage, this electromagnetic switch turns the motor on and off while protecting the electrical circuit from overcurrent. The contactor is a critical safety and control component in Hyster electric lift trucks.
Q: What is the voltage and amperage rating for the HY 349975 contactor?
A: The HY 349975 is rated for 180 amperes continuous duty, with a 12VDC control coil voltage. The 12VDC specification refers to the coil control circuit that energizes and de-energizes the contactor. Do not apply line voltage directly to the coil. The contact rating of 180A handles the high-current motor load.
Q: Which Hyster models use the HY 349975 contactor?
A: The HY 349975 is compatible with various Hyster electric pallet truck and lift truck models. It replaces the earlier Hyster 1330938 contactor and is equivalent to aftermarket 349975 models. Verify your equipment serial range and electrical specifications before ordering to ensure correct fitment.
Q: What is the cross-reference or superseded part number for the HY 349975?
A: The HY 349975 replaces and supersedes the earlier Hyster 1330938 contactor. If your equipment calls for part number 1330938, the HY 349975 is the current equivalent OEM replacement. Both parts have the same voltage and amperage ratings and panel-mount configuration.
Q: What material are the HY 349975 contacts made from?
A: The HY 349975 features heavy-duty copper alloy contacts that are designed to withstand the high current and repeated switching cycles required in lift truck motor control. The base mounting frame is glass-filled phenolic, providing electrical insulation and mechanical durability. This construction ensures long service life in continuous-duty industrial applications.
Q: What are signs that the HY 349975 contactor needs replacement?
A: Failure signs include motor not responding to control input, chattering or buzzing sounds from the contactor, inability to power the lift mechanism, or intermittent operation. Worn or burned copper contacts may cause high resistance and power loss. If the truck does not respond when the drive button is pressed, the contactor should be tested and replaced if faulty.
