The C25H6TM160C is a 4-pole ComPacT NSX250H moulded-case circuit breaker with a thermal-magnetic TM-D trip unit rated 160 A at 50 °C. At 220/240 V the same breaker is rated 100 kA Icu, so it handles high-fault points near the service entrance without cascading upstream. No earth-leakage module is integrated, so if ground-fault protection is required on the distribution board, a separate Vigi add-on or external relay is needed.
Front connections both top and bottom simplify bus-bar and cable routing in a distribution panel. The 140 mm width and 161 mm height fit standard ComPacT NSX cutouts; depth is 86 mm. IK07 impact resistance handles incidental tool contact during panel work.
Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V at rated current (In). At half-load (In/2) at 440 V, electrical durability doubles to 20,000 cycles. At 690 V, expect 5,000 cycles at In. These figures matter for frequent switching applications like capacitor bank or lighting contactor duty — if the breaker cycles daily, the mechanical endurance sets the replacement interval.
