Product details

63 A, 4-pole MCCB with TM-D trip unit

The Schneider Electric C11F4TM063B is a ComPacT NSXm 63F molded-case circuit breaker rated 63 A at 40 °C with four poles (4P), a thermal-magnetic TM-D trip unit, and a 36 kA interrupting capacity at 415 V AC (performance level F). This is a distribution-grade MCCB built to EN/IEC 60947-2, Category A — it is not current-limiting by design, so coordination studies should account for full let-through on bolted faults below its rated breaking capacity.

The 4P configuration switches all four poles (three phases plus neutral), with the neutral pole on the left side of the breaker.

The 108 mm width occupies 12 module pitches of 9 mm. Connection is front-facing via compression lugs or busbars; connection pitch is 35 mm with spreaders, 27 mm without. The toggle handle provides manual control, and a green flag signals presence of auxiliary contacts. IP40 enclosure protection and IK07 impact resistance suit it for panel-mount applications in clean industrial environments.
