Product details

The C10B4TM063C is a Schneider Electric ComPacT NSX100B four-pole (4P) circuit breaker with a TM-D thermal-magnetic trip unit rated 63 A at 50 °C. It belongs to the ComPacT NSX family, a modular MCCB platform for distribution and motor-circuit protection in commercial and industrial panels. The 40 kA Icu at 240 V AC (25 kA at 415 V, 20 kA at 440 V, 15 kA at 500 V) covers most facility-level fault-current scenarios without requiring a current-limiting upstream device.

IK07 impact resistance handles accidental tool drops during installation. The 50000-cycle mechanical durability and 30000-cycle electrical durability at rated current give a long service life in normal switching duty.

Mounts flat on a backplate in horizontal or vertical orientation. Front connections both upside and downside simplify bus-bar and cable routing in a panel. The 35 mm connection pitch matches standard bus-bar spacing. Neutral sits on the left.
