Motor protection circuit breaker for panel builders
Rated breaking capacity hits 100 kA at 400 V and 500 V, and 100 kA at 240 V — that is the SCCR the breaker can safely interrupt under fault conditions, which sets the panel's short-circuit current rating.
Terminals accept 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire. Main contact terminals are M3 screw type. Clearance distances: 50 mm upwards and downwards, 30 mm at the sides — factor those into your enclosure sizing for heat dissipation and arc-flash clearance.
