C120N Circuit Breaker 4P 125A Curve C 10kA

This Acti9 C120N is a low-voltage multi-standard miniature circuit breaker (MCB). It is a 4P circuit breaker with 4 protected poles, a rated current of 125A, and a C tripping curve. The rated short-circuit breaking capacity reaches 10,000 A at 230 V AC up to 400 V AC in accordance with EN/IEC 60898-1 and 10,000 A at 230 V AC up to 400 V AC in accordance with EN/IEC 60898-1. It complies with both the industrial standard EN/IEC 60898-1 and the residential standard EN/IEC 60947-2. This miniature circuit breaker combines circuit protection functions against short-circuit and overload current, control and isolation. The presence of green strips ensures a physically open contact and allows work to be carried out safely on the downstream circuit. It has good surge withstand capability. The product is designed to offer a high level of industrial performance. It has an electrical endurance of up to 5000 cycles and a mechanical endurance of up to 20000 cycles. The operational voltage Ue ranges from 380VAC to 415VAC. The rated insulation voltage Ui is 500VAC. Its class of limitation 3 (according to EN/IEC60898-1) enhances the cost of protection for the downstream circuit. The product can be mounted on a DIN rail. Its width is 12 modules of 9mm. The pollution degree is 3. The overvoltage category is IV. The product colour is white (RAL9003). The dimensions are (W) 108 mm x (H) 81 mm x (D) 73 mm. The weight is 0.82 kg. It has an IP20 degree of protection (according to IEC/EN 60529) at its terminals. The operating temperature is from -25°C to 70°C. The storage temperature is from -40°C to 85°C.
