Motor protection circuit breaker for Class 10 trip curves
Rated for a supply voltage range of 20 to 690 V, this breaker delivers a short-circuit breaking capacity of 100 kA at 400 V and 500 V, and 10 kA at 690 V. At 400 V, the gL/gG fuse backup rating is 25 A. That SCCR headroom means it can be applied on high-fault-capacity distribution panels without cascading upstream — a key coordination point for the site electrical engineer. No ground fault detection on this variant.
DIN rail integration and wiring
Dimensions are 97 mm deep, 45 mm wide, and 106 mm tall. Clearance requirements: 50 mm upwards and downwards, 30 mm to the side. Main circuit connections use spring-loaded terminals accepting 2× (0.5 to 2.5 mm²) solid or stranded wire. No screw torque to verify — just strip to the right length and push in. The spring cage holds the conductor under vibration, which matters on a machine-side panel near a press or conveyor.
The breaker can be stored in unheated warehouses and still perform when pulled for a line-down swap.
