Frequently Asked Questions
Q: What are the current ratings for the AL SW180-4 contactor?
A: The AL SW180-4 is rated for 150A interrupted and 200A uninterrupted current in standard applications. For intermittent duty cycles: 275A at 30% duty, 210A at 50% duty, and 180A at 70% duty. The unit can break up to 1000A fault current at 96VDC with magnetic blowouts installed.
Q: What coil voltage does the AL SW180-4 require?
A: The AL SW180-4 operates on 24VDC coil voltage. It uses 6.3mm spade connections for the coil terminals, making it compatible with standard 24V control systems on electric lift trucks and industrial vehicles.
Q: What terminal types does the AL SW180-4 use?
A: The main circuit terminals are M8 studs, which are standard on most electric lift truck contactors. The coil connections are 6.3mm spades for compatibility with common DC control harnesses.
Q: What contact material is used in the AL SW180-4?
A: The contactor features silver alloy contacts designed for high-speed switching and reliable conductivity in DC circuits. Silver alloy contacts provide superior arc resistance and lower contact resistance compared to standard copper contacts.
Q: Is the AL SW180-4 suitable for electric lift truck applications?
A: Yes. The SW180-4 is engineered for electric lift trucks, reach trucks, and other DC industrial vehicles requiring solid-state switching at 24VDC. Verify your equipment uses 24V coil control and operates within the rated current parameters.
