Product details

Motor-protection MCCB with magnetic-only trip

That trip unit is designed for short-circuit protection only — no thermal overload element — making this breaker a match for motor branch circuits where the overload relay handles the running protection and the MCCB clears faults. The 85 kA Icu at 500 V AC (75 kA at 690 V AC) gives it the interrupting capacity to sit upstream of a motor starter without cascading into the contactor during a bolted fault.

Rated 85 kA Icu at 500 V AC, 80 kA at 525 V AC, and 75 kA at 690 V AC per IEC 60947-2. That HB1 breaking-capacity code (75 kA at 690 V) means this breaker can be applied on 480/600 V class systems with headroom for high-fault installations. The 3-pole, 3D protected-pole configuration suits three-phase motor circuits. Electrical durability is 20,000 cycles at 440 V In/2 and 10,000 cycles at 440 V In — enough for frequent motor starting in conveyor or pump duty.
