Frequently Asked Questions
Q: What is the QU-ICOM611AC12A contactor used for?
A: The QU-ICOM611AC12A is a 12-volt contactor designed for auxiliary and control circuit switching in electric lift trucks and powered pallet jacks. It provides single pole, single throw control for 12VDC solenoids, motors, and lighting circuits in material handling equipment.
Q: What is the coil voltage rating of the QU-ICOM611AC12A?
A: The QU-ICOM611AC12A operates at 12VDC coil voltage. The contactor coil must receive exactly 12 volts DC to energize and pull in properly. If your equipment power supply is 24VDC or uses alternating current, this contactor is not compatible. Verify your system voltage before ordering.
Q: Which electric lift truck and pallet jack models accept the QU-ICOM611AC12A?
A: The QU-ICOM611AC12A is compatible with 12VDC auxiliary and control circuits in electric lift trucks and pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEM manufacturers. Confirm your equipment control system voltage and contactor application before ordering.
Q: What happens if the QU-ICOM611AC12A contactor fails to energize?
A: If the contactor fails to energize, the associated circuit (solenoid, motor, or light) will not function. Troubleshoot by: verifying 12VDC is present at the coil terminals, testing for burned-out coil windings with a resistance meter, checking for burnt contacts if energizing occurs but device does not switch. Replace the QU-ICOM611AC12A if the coil is open or contacts are welded.
Q: What is the expected service life of the QU-ICOM611AC12A contactor?
A: The QU-ICOM611AC12A typically sustains 1 to 3 million electrical operating cycles under rated load conditions. Actual lifespan depends on switching frequency, circuit current, environmental contamination, and maintenance. Monitor for contact pitting, noise during operation, or sluggish response as wear indicators.
