Rated for breaking capacities of 100 kA at 240 V, 13 kA at 400 V, 3 kA at 500 V, and 2 kA at 690 V, this breaker handles fault currents typical in industrial motor circuits. Screw-type terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded copper, which covers most motor branch-circuit wiring sizes.
Mounting and Fit
At 45 mm wide and 90 mm tall, this breaker occupies a single modular space on the DIN rail. The 75 mm depth leaves clearance for wiring behind the panel door. Mounting position is any orientation; the specified clearances are 20 mm upward and downward, 9 mm to the side, and 0 mm forward or backward — meaning it can sit tight against the backplane.
