Motor protection circuit breaker with Trip Class 10 and 100 kA breaking capacity
The 100 kA breaking capacity at 400 V AC and at 240 V, 500 V, and 690 V means this breaker can safely interrupt fault currents up to that level without upstream fuses or a larger breaker — a key spec for high-fault-capacity industrial panels where the available short-circuit current at the motor starter exceeds 50 kA. The 45 mm width and 97 mm depth fit the standard SIRIUS 3RV2 footprint, and the screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715 means it clips directly into a panel alongside contactors and overload relays without extra brackets.
Mounting and integration into a motor starter panel
The screw-type terminals on the main current circuit accept 2× (0.75 to 2.5 mm²) solid or stranded, or 2× 4 mm², with M3 screws for the main contacts. Clearance distances: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards — the zero forward/backward clearance means it can be mounted flush against a backplate or enclosure wall without derating.
