The C25H4TM200C is a Schneider Electric ComPacT NSX250H moulded-case circuit breaker with a 200 A thermal-magnetic trip unit (TM-D) and a 4-pole (4P) configuration.
The breaking capacity curve is the deciding factor for panel coordination. At 220/240 V AC the C25H4TM200C delivers 100 kA Icu; at 380/415 V AC it holds 70 kA Icu; at 440 V AC it drops to 65 kA Icu; at 500 V AC to 50 kA Icu; at 525 V AC to 35 kA Icu; and at 660/690 V AC to 10 kA Icu. The utilisation category is A, meaning it is not intended for frequent switching of motor loads — it is a distribution breaker, sized for feeder and branch-circuit protection where the fault current the source can deliver is the binding constraint.
Mounting and physical integration
Dimensions are 161 mm high by 140 mm wide by 86 mm deep. IP40 enclosure protection keeps dust and tools out; IK07 impact resistance handles incidental knocks during panel assembly.
