The C25F6TM200C is a Schneider Electric ComPacT NSX250F molded case circuit breaker, 4-pole, with a TM-D thermal-magnetic trip unit rated at 200 A at 50 °C. It is designed for distribution applications and carries an 85 kA Icu breaking capacity at 220/240 V AC, derating to 36 kA at 415 V and 8 kA at 690 V.
At 690 V the Icu drops to 8 kA, so if your secondary side runs at that voltage, verify the available fault current against the curve. The 200 A frame (NSX250F) with TM-D trip provides L and I protection: thermal overload (L) and magnetic short-circuit (I). No earth-leakage module is fitted (without).
Mounts on a backplate, accepts front (upside and downside) connections. The 4-pole unit has neutral on the left with 3D protection (no neutral protection). Toggle control, IP40 enclosure, IK07 impact resistance.
