Product details

The C10W3TM063 is a Schneider Electric ComPacT NSX circuit breaker rated 63 A at 40 °C, three-pole, with a TM-D thermal-magnetic trip unit providing overload (L) and short-circuit (I) protection. Its 100 kA Icu at 690 V AC (EN/IEC 60947-2) means it safely interrupts fault currents up to that level without upstream cascading — a key figure for high-fault-capacity distribution panels where SCCR headroom is non-negotiable.

The 63 A trip unit rating at 40 °C is the continuous current the breaker carries without tripping — sized for a 63 A feeder or downstream load center. The 100 kA Icu at 690 V AC (HB2 breaking capacity code) covers high-fault installations like industrial substations or large motor control centers. The thermal-magnetic TM-D trip unit gives fixed overload protection (thermal) and fixed short-circuit protection (magnetic) — no interchangeable modules, so the trip curve is set at the factory.

Mounts on a backplate in horizontal or vertical orientation — no DIN-rail clip, so panel builders need a drilled backplate or a mounting adapter. The 35 mm connection pitch matches standard busbar systems. Front-connect terminals on both line and load sides simplify wiring in a panel with limited access.
