Product details

Overview

The C25R4TM125 is a Schneider ComPacT NSX molded case circuit breaker rated 125 A at 40 °C with a 200 kA ICu breaking capacity at 690 V AC, built on the NSX250R frame. It carries a thermal-magnetic TM-D trip unit providing L (overload) and I (short-circuit) protection, and is classified as Category A per IEC 60947-2.

Compared to the C10F3TM025 (3-pole, 25 A, 85 kA ICu), the C25R4TM125 delivers 4-pole switching at 125 A with a 200 kA ICu — a step up in both pole count and fault-current handling for distribution panels requiring higher SCCR.
