This Acti9 C120N is a low voltage multistandard miniature circuit breaker (MCB). It is a 4P circuit breaker with 4 protected poles, 125A rated current and B tripping curve. The Icn rated short circuit breaking capacity goes up to 10000A at 230VAC to 400VAC conforming to IEC/EN 60898-1 standard. This product complies with industrial standard IEC/EN 60898-1 and residential standard IEC/EN 60947-2. This miniature circuit breaker protects circuit against short circuit and overload current. The presence of green strip guarantees contact open physically and allows work to be carried out safely on the downstream circuit. It has an electrical endurance going up to 5000 cycles and a mechanical endurance going up to 20000 cycles. The Ue operational voltage is going from 380VAC to 415VAC. The Ui rated insulation voltage is 500VAC. Its limitation class 3 (according to IEC/EN 60947-2 standard) improves downstream circuit protection cost. The product can be clipped on a DIN rail. Its width is 12 pitches of 9mm. Pollution degree is 3. Overvoltage category is IV. The product colour is white (RAL 9003). The dimensions are (W) 108mm x (H) 81mm x (D) 73mm. The weight is 0.82kg. It has an IP20 degree of protection (as per IEC 60529 standard) on its terminals. The operating temperature is from -25°C to +70°C. The storage temperature is from -40°C to +85°C.
