Overview
The C10V4TM063 is a Schneider ComPacT NSX molded case circuit breaker with 4 poles, rated 63 A at 40 °C via a thermal-magnetic TM-D trip unit, and an 85 kA ultimate breaking capacity (Icu) at 690 V AC. It is a fixed-mount, toggle-operated distribution breaker compliant with EN/IEC 60947-2, carrying a Class II front face and IK07 impact rating.
How it compares
Compared to the 3-pole C10F3TM025 (25 A, 25 kA Icu), the C10V4TM063 adds a fourth pole, more than doubles the continuous rating to 63 A, and triples the breaking capacity to 85 kA — a step up in both fault-handling and load capacity for 4-wire distribution.
