Product details

Overview

The C25R4TM250 is a Schneider ComPacT NSX molded case circuit breaker rated 250 A at 40 °C across 4 poles, with a 200 kA ultimate breaking capacity (ICu) at 690 V AC. It carries a TM-D thermal-magnetic trip unit providing overload (L) and short-circuit (I) protection for distribution applications. The fixed-mount design uses a toggle actuator and front-face connections.

Compared to the C10F3TM025 (3-pole, 25 A, 85 kA ICu), the C25R4TM250 adds a fourth pole and jumps to 250 A continuous with 200 kA ICu — a step up in both current handling and fault capacity. The C10F3TM025 suits smaller 3-phase loads; the C25R4TM250 is for high-fault 4-wire distribution panels.
