What is the Schneider Electric A9N18355?

This Acti9 C120N product is a low-voltage miniature circuit breaker (MCB). It is a 4P circuit breaker with 4 protected poles, 125A rated current and a B tripping curve. The rated short circuit breaking capacity goes up to 10000A at 400VAC, conforming to IEC/EN 60898-1 standard. This product complies with residential standard IEC/EN 60898-1 and industrial standard IEC/EN 60947-2. It combines functions of circuit protection against short circuit and overload current, control and isolation. The presence of a green strip guarantees contact open physically and allows work to be carried out safely on the downstream circuit. It is designed to offer a high industrial performance level. It boasts exceptional durability, with electrical endurance reaching up to 5000 cycles and mechanical endurance extending to 20000 cycles. The rated operational voltage is from 380VAC to 415VAC. The rated insulation voltage is 500VAC, and the rated impulse withstand voltage is 6kV. Additionally, its limitation class 3 enhances the downstream circuit protection cost, while the pollution degree 3 ensures reliable performance in challenging environments. It can be mounted on a 35mm symmetrical DIN rail. The width in 9mm pitches is 12. The dimensions are (W) 108mm x (H) 81mm x (D) 73mm. The product colour is white. The weight is 0.82kg. It offers reliable protection with an IP20 rating on its terminals. The operating temperature is from -25°C to 70°C. The storage temperature is from -40°C to 85°C.
