Frequently Asked Questions
Q: What are the electrical specifications of the YL 501270304?
A: The YL 501270304 features a 12VDC coil rated for continuous duty. Current rating is 150A make (closing) and 100A break (opening) at 12VDC. Insulator material is molded phenolic with brass terminal studs and copper alloy contacts for reliable switching performance.
Q: What is the duty cycle rating for this contactor solenoid?
A: The YL 501270304 is rated for intermittent duty cycle: 30 seconds ON followed by 5 minutes OFF. Do not operate continuously beyond this cycle without allowing adequate cooling time between engagement periods.
Q: Are there cross-reference part numbers for the YL 501270304?
A: Yes. Cross-reference part numbers include YT501270304-ORG and 501270304-ORG. The YL 501270304 is equivalent to White Rodgers type contactors with the same electrical and physical specifications. Confirm dimensions match your mounting location.
Q: Which Yale lift truck models use this contactor?
A: The YL 501270304 is compatible with Yale electric lift trucks and pallet jacks that operate 12-volt control circuits. Verify your equipment electrical system and solenoid mounting dimensions before ordering.
Q: What is the difference between the make and break ratings?
A: The make rating (150A) is the maximum current the solenoid can safely carry when closing contacts. The break rating (100A) is the maximum current it can safely interrupt. The break rating is lower because breaking a current-carrying circuit generates more heat in the contacts than closing an unpowered circuit.
Q: How long does this solenoid typically last before failure?
A: Service life depends on switching frequency and load conditions. In intermittent duty use, expect 3–5 years of reliable operation. High-frequency switching, sustained overloads, or exposure to moisture will reduce lifespan. Monitor for wear-in of contact surfaces.
