CONTACTOR (24 VOLT)
Frequently Asked Questions
Q: What is the coil voltage specification for the 828-37023?
A: The 828-37023 is a 24-volt DC contactor. The 24VDC coil energizes the solenoid armature to close the main power contacts. Control voltage must be stable between 20 and 28 volts for reliable pull-in and drop-out.
Q: How does the 828-37023 differ from the 828-36003?
A: Both are 24-volt contactors for electric lift trucks. The 828-37023 may differ in contact material, amperage rating, or auxiliary contact configuration. Before cross-using these parts, verify main contact amperage (200 to 400 amps), number of auxiliary contacts (0 to 4), and case dimensions against the truck schematic and existing contactor.
Q: What symptoms indicate the 828-37023 contactor is failing?
A: Failing contactors show buzzing or chattering sounds when energized, incomplete motor engagement, or motor hum without movement. If the truck accelerates slowly or hesitates during lift, or if the joystick shows no motor response on first press, suspect contactor contact wear or coil failure. Replace the 828-37023 to restore reliable performance.
Q: How often does the 828-37023 need replacement in high-duty applications?
A: In continuous-shift warehouse operations (16 to 24 hours daily), plan to replace the 828-37023 every 6 to 9 months. In standard warehouse use (8 to 10 hours daily), expect 12 to 24 months of service life. Contact erosion accumulates faster in cold storage and wet environments.
Q: What is the main contact amperage rating of the 828-37023?
A: The 828-37023 is typically rated for 200 to 300 amps continuous on the main motor circuit at 24VDC to 80VDC, depending on contact design. Do not overload beyond the nameplate rating. Oversized motors or series-parallel circuits that draw above the rated amperage will damage the contacts in weeks.
