The C10B3TM025 is a Schneider Electric ComPacT NSX100B moulded-case circuit breaker — 3-pole, 25 A frame, fitted with a TM-D thermal-magnetic trip unit. The 25 kA Icu at 380/415 V AC is the interrupting capacity you coordinate downstream — it clears a fault up to that level without welding contacts or rupturing the case, per IEC 60947-2. Pollution degree 3 means it tolerates conductive pollution in a control-panel environment — no special sealing needed for the typical industrial enclosure.
Mounts flat on a backplate in horizontal or vertical orientation. Front connections on both line and load sides keep wiring accessible inside the enclosure. The 105 mm width and 161 mm height fit standard MCCB panel cutouts; the 86 mm depth leaves room for rear busbar or cable routing. Rated for isolation per EN/IEC 60947-2 — you can use it as a visible-break disconnect for downstream maintenance, provided the handle padlocks in the OFF position.
