The Schneider Electric C25H3TM200C is a ComPacT NSX250H moulded-case circuit breaker (MCCB) from the NSX family, rated 200 A at 50 °C with a 3-pole, thermal-magnetic TM-D trip unit. It carries a 70 kA Icu breaking capacity at 415 V AC (50/60 Hz) per IEC 60947-2, and is listed as suitable for isolation per that same standard.
The Icu curve drops as voltage rises: 100 kA at 240 V AC, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, and 10 kA at 690 V.
IP40 front face (finger-safe), IK07 impact resistance.
The TM-D trip unit provides thermal-magnetic protection: thermal (L) for overload, magnetic (I) for short-circuit. No earth-leakage protection built in — add a Vigi module externally if required. Rated 200 A at 50 °C; no derating data provided above that, so keep ambient below 50 °C or consult the thermal curve. Power dissipation is 15.4 W per pole (46.2 W total at full load) — factor that into the enclosure heat budget. Electrical durability: 20,000 cycles at 440 V In/2, 10,000 at 440 V In; mechanical durability 20,000 cycles.
