Frequently Asked Questions
Q: What are the electrical specifications for the AL SW180L-48?
A: The AL SW180L-48 is rated for 36/48VDC coil voltage with 150A continuous and 200A intermittent contact rating. Rated fault current breaking capacity at 48VDC meets or exceeds 1000A under appropriate load conditions. The contactor is designed for 6 to 80 VDC contact circuit voltage operation in demanding industrial applications.
Q: What electric lift truck applications is the AL SW180L-48 designed for?
A: The AL SW180L-48 is engineered for electric lift truck applications requiring direct current load switching and motor control. It is compatible with material handling equipment from Crown, Toyota, Raymond, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT across 36-volt and 48-volt DC systems.
Q: What are the cross-reference and equivalent part numbers for AL SW180L-48?
A: Cross-reference part numbers include ALSW180L-48, ALSW180L48, SW180L48, and equivalent parts SW180-48, ALSW180-48, ALSW18048, and SW18048. The manufacturer part number is AL SW180L-48 and the OEM part number is SW180L-48. Verify coil voltage and current ratings match your equipment when sourcing alternatives.
Q: What contact configuration and material are used in the AL SW180L-48?
A: The AL SW180L-48 features M8 stud main terminals with double breaking silver alloy contacts. The double breaking design provides superior arc suppression and contact separation during heavy load switching, while the silver alloy material resists welding and erosion through thousands of industrial operating cycles.
Q: How many mechanical operations does the AL SW180L-48 support?
A: The AL SW180L-48 exceeds five million mechanical operations, delivering dependable service life in demanding electric lift truck applications. The robust double breaking contact design and welded-resistant silver alloy materials maintain performance and reliability through extended cycling and continuous industrial use.
Q: What maintenance and monitoring steps should be followed for this contactor?
A: Inspect M8 terminal connections regularly for corrosion, oxidation, or loose fittings, particularly in wet or cold storage environments. Monitor coil voltage periodically to confirm it meets rated 36/48VDC specification. If the contactor does not pull in at rated voltage, exhibits slow response, or shows signs of contact erosion, contact us for replacement evaluation and assistance in sourcing the correct replacement.
