Frequently Asked Questions
Q: What is the coil voltage and current rating for the AL SW180L-24 contactor?
A: The AL SW180L-24 features a 24VDC coil with a 150A continuous thermal current rating and 200A intermittent capacity. Typical voltage drop per pole is 40 mV at 150A, and the pull-in voltage maximum in intermittent mode is 60 percent of rated coil voltage. This contactor is rated for 6 to 80 VDC contact circuit voltage.
Q: What equipment compatibility does the AL SW180L-24 have?
A: The AL SW180L-24 is engineered for electric lift truck hydraulic contactor applications and industrial vehicle motor control. It functions as a single pole single throw (SPST) relay with double breaking contacts designed for robust performance in demanding electric material handling equipment from manufacturers such as Crown, Toyota, Raymond, and similar industrial lift truck platforms.
Q: What are the cross-reference and equivalent part numbers for AL SW180L-24?
A: Cross-reference part numbers include ALSW180L-24, ALSW180L24, SW180L24, and equivalent parts SW180-241 and SW180-448L. The OEM part number is SW180L-24. When ordering replacement or interchangeable contactors, verify that coil voltage and current ratings match your equipment specifications.
Q: What terminal type and material are used in the AL SW180L-24?
A: The AL SW180L-24 features M8 main stud terminals with welded-resistant silver alloy double breaking contacts. The silver alloy construction provides excellent conductivity and arcing resistance, delivering reliable performance through thousands of load-switching cycles in industrial vehicle applications.
Q: What is the mechanical durability and lifespan of the AL SW180L-24?
A: The AL SW180L-24 is rated for over 5,000,000 mechanical operations, ensuring long service life under continuous industrial use. The double breaking silver alloy contacts resist welding and erosion, maintaining performance through extended operation in electric lift truck and material handling vehicle applications.
Q: What maintenance or periodic checks are recommended for this contactor?
A: Inspect M8 terminal connections periodically for corrosion or loose fittings, particularly in wet or cold storage environments. Monitor coil voltage and contact resistance during equipment service intervals. If contactor does not pull in at rated voltage or drops voltage below pull-in threshold, replacement may be necessary. Clean terminals with appropriate electrical contact cleaner if visible oxidation appears.
