The C25W3TM200 is a Schneider Electric ComPacT NSX250HB2 moulded-case circuit breaker, 3-pole, with a thermal-magnetic TM-D trip unit rated 200 A at 40 °C. The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection, with no earth-leakage module built in.
IP40 enclosure protection means it is suited for indoor, dry locations — not washdown or outdoor.
Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V at rated current (In/2). At full rated current (In) at 440 V, electrical durability drops to 10,000 cycles. At 690 V, expect 10,000 cycles at In/2 and 5,000 cycles at In. That is typical for a distribution-grade MCCB — not intended for frequent switching duty like a contactor, but fine for infrequent on-load switching and fault protection.
