Square D LA magnetic only molded case circuit breakers (Mag-Gard) provide motor circuit protection. They are designed as disconnect devices for use in combination with motor starts. They are magnetic detection so provide short circuit protection only. This Square D LA Mag-Gard is 3 pole unit mount, 400A and 600VAC, with lugs. Mag-Gard circuit breakers have an adjustable amperage pick up so can be set to open instantaneously to coordinate with the motor.

• Features
• LA molded case 400A, 600VAC 3 poles unit mount motor circuit protector
• Designed to control the motor (ON/OFF) either manually, automatically or remotely, taking into account overloads
• Magnetic trip unit only provides short circuit protection.
• Adjustable amperage pick can be set to open instantaneously at current slightly above the motor starting inrush curren
• The LA-frame motor circuit protector is compliant with standards IEC 60947-2 and UL 508/CSA 22.2 N°14, UL 489.
• Shunt trip is used to trip the circuit breaker from a remote location with a trip coil energized from a separate circuit
• Circuit breaker has factory installed UL listed mechanical aluminum alloy suitable for aluminum or copper wire
• UL 489, CSA, IEC certified
• Prop 65
