Frequently Asked Questions
Q: What coil voltage options does the AL SW180B-48 provide?
A: The AL SW180B-48 operates on either 36VDC or 48VDC continuous duty. Specify your equipment voltage when ordering. This contactor is engineered for high-voltage lift truck and industrial vehicle applications.
Q: What is the continuous current rating for the AL SW180B-48?
A: The contactor is rated for 150A continuous duty at 48VDC. This rating is suitable for motor drive circuits, main battery disconnect, and power distribution in 48V electric lift trucks and reach trucks.
Q: What coil power dissipation does the AL SW180B-48 require?
A: The contactor coil dissipates 10 to 15 watts during continuous operation. This power draw is typical for 36V and 48V solenoid coils and should be verified against your vehicles control system capacity.
Q: What contact configuration does the AL SW180B-48 use?
A: The AL SW180B-48 features single pole, single throw normally open contacts with silver alloy materials. The contacts are designed for reliable DC switching and built to withstand frequent duty cycling in lift truck applications.
Q: Does the AL SW180B-48 include magnetic blowouts?
A: Yes. Magnetic blowouts are included to enhance current-breaking performance and arc extinction during high-current switching events, which is critical in industrial lift truck DC circuits.
Q: What mounting options are available for the AL SW180B-48?
A: The contactor can be mounted horizontally or vertically using M5 tapped fastening holes. M8 stud main terminals accept standard DC contactor connectors and harnesses found on electric lift trucks from Crown, Toyota, Raymond, Hyster, and Yale.
