Product details

The C25N4TM160C is a 4-pole ComPacT NSX250N circuit breaker with a thermal-magnetic TM-D trip unit rated 160 A at 50 °C. The 4P configuration with neutral protection set at 1 x Ir (full-rated) suits it for distribution boards where the neutral conductor must be protected at the same level as the phases. The thermal element tracks RMS current for overloads; the magnetic element responds instantaneously to short-circuit peaks. Category A utilisation means it is not intended for frequent switching of motor loads — it is a distribution breaker, not a motor-starter combination.

Deployment context

The 161 mm height, 140 mm width, and 86 mm depth fit standard panel cutouts for the NSX250 frame. Front connections on both upside and downside simplify busbar and cable routing.

Electrical durability: 20,000 cycles at 440 V In/2, 10,000 cycles at 440 V In, 10,000 cycles at 690 V In/2, 5,000 cycles at 690 V In. Mechanical durability: 20,000 cycles. Relative humidity 0–95 %.
