Frequently Asked Questions
Q: What are the current ratings for the AL SW180-24 at various duty cycles?
A: At 30 percent duty cycle the AL SW180-24 handles 275A, at 40 percent it handles 235A, at 50 percent it handles 210A, at 60 percent it handles 195A, and at 70 percent it handles 180A. These are intermittent duty ratings. Verify your application duty cycle matches these specifications.
Q: What is the fault breaking capacity for the AL SW180-24?
A: The AL SW180-24 is rated for 1000A fault breaking capacity at 48VDC without blowouts and 1000A at 96VDC (with optional magnetic blowout configuration). This high fault rating protects motor circuits from damage.
Q: What terminal configuration does the AL SW180-24 have?
A: The AL SW180-24 features M8 stud terminals for main power connections and 6.3 mm spade coil connections. These standard terminals fit Crown, Toyota, Raymond, Yale, and other electric lift truck models.
Q: What coil voltage is the AL SW180-24 rated for?
A: The AL SW180-24 operates on 24VDC coil voltage. This is a common voltage standard in electric lift trucks and industrial motor control applications. Verify your equipment requires 24VDC before ordering.
Q: What is the mechanical durability of the AL SW180-24?
A: The AL SW180-24 is rated for five million mechanical cycles with durable silver alloy contacts. This high cycle rating supports frequent motor switching in industrial lift trucks and material handling equipment.
