The C25W32M150 is a Schneider Electric ComPacT NSX circuit breaker, 3-pole, rated 150 A at 65 °C with a MicroLogic 2.2 M electronic trip unit. It delivers 100 kA Icu at 690 V AC 50/60 Hz per IEC 60947-2, making it suitable for high-fault motor circuits where coordination with downstream starters is critical.
The MicroLogic 2.2 M provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection, with selectable motor tripping classes 5, 10, or 20.
Breaking capacity and duty
Rated 100 kA Icu at 500 V AC, 525 V AC, and 690 V AC (50/60 Hz) per IEC 60947-2, this breaker handles high available fault current without cascading upstream. Electrical durability is 20,000 cycles at 440 V In/2 and 10,000 cycles at 440 V In; mechanical durability is 20,000 cycles. The utilisation category is A, meaning it is not intended for frequent switching of motor loads under load — that is the starter's job.
IP40 front face, IK07 impact resistance. Operating altitude 0–2000 m without derating, 2000–5000 m with derating. The 35 mm connection pitch and front-facing terminals simplify panel wiring.
