The C10B3TM063 is a 3-pole ComPacT NSX100B circuit breaker with a TM-D thermal-magnetic trip unit rated 63 A at 40 °C. Thermal-magnetic protection (L for overload, I for short-circuit) means no electronic trip unit to program or power — it's a passive, field-reliable design.
Deployment context
Mounts on a backplate (not DIN rail) in any orientation — horizontal, vertical, or flat on the back. The 105 mm width and 161 mm height fit standard ComPacT NSX cutouts. Front connections on both line and load sides simplify busbar or cable routing in a distribution panel.
