Frequently Asked Questions
Q: What voltage and current specifications does the AL SW180-39BL have?
A: The AL SW180-39BL is a 36/48VDC contactor with a 150A thermal rating and 200A uninterrupted current rating. Thermal rating applies to continuous duty; uninterrupted rating is for short-term operation. Choose based on your lift truck duty cycle.
Q: What coil voltage options are available for the AL SW180-39BL?
A: The AL SW180-39BL offers coil voltage options of 36VDC or 48VDC. Coil power consumption is 11 to 14W nominal for continuously rated types, or 10 to 15W for other configurations. Specify your required coil voltage when ordering.
Q: What contact material and terminal types does the AL SW180-39BL use?
A: The AL SW180-39BL features double-breaking main contacts with silver alloy tips for heavy-duty DC switching. Main terminals are M8 studs; coil connection uses 6.3mm spades. Silver alloy contacts resist pitting and erosion better than standard copper contacts in high-cycle applications.
Q: Can the AL SW180-39BL be mounted horizontally or vertically?
A: Yes, the AL SW180-39BL supports both horizontal and vertical mounting orientations. Orientation does not affect electrical performance but may affect thermal dissipation, so verify clearance for airflow around the contactor.
Q: How durable is the AL SW180-39BL under heavy-duty service?
A: The AL SW180-39BL is rated for mechanical durability exceeding 5 million cycles. Double-breaking contacts and silver alloy tips extend contact life in high-frequency switching applications. Actual lifespan depends on load characteristics and terminal maintenance.
Q: Is the AL SW180-39BL compatible with Crown, Toyota, Raymond, or other lift truck brands?
A: The AL SW180-39BL is an Albright SW180 series contactor compatible with multiple electric lift truck OEMs. Verify your truck model uses M8 stud main terminals and 6.3mm spade coil connectors before ordering. Cross-reference your current contactor part number for compatibility.
