Product details

The Schneider Electric C11B3TM100B is a ComPacT NSXm 3-pole moulded-case circuit breaker rated 100 A at 40 °C with a 25 kA breaking capacity at 415 V AC (performance level B).

It occupies 9 module pitches at 81 mm width, 137 mm height, 80 mm depth — fits standard 160 A frame cutouts. Connection is front-facing via compression lugs or busbars; the 35 mm pitch with spreaders (27 mm without) matches common busbar layouts. IP40 enclosure protection and IK07 impact resistance suit indoor distribution boards.

Thermal-magnetic trip (TM-D) provides fixed overload protection and magnetic short-circuit response — no adjustment, so coordination studies rely on the published trip curve. Suitability for isolation per IEC 60947-2 means the breaker can be used as a disconnecting means in the circuit. Power dissipation is 7.5 W per pole (22.5 W total at full load) — factor into enclosure thermal calculations.
