Schneider Electric Circuit Breaker – A9N18372

The Acti 9 C120N is a low-voltage circuit breaker (MCB). This product is a 4P circuit breaker with 4 protected poles. It has a nominal current of 80A and a C cut-off characteristic. The breaking capacity at 230VAC to 400VAC is 10000A according to EN/IEC 60898-1. The breaking capacity at 380VAC to 415VAC is 10kA according to EN/IEC 60947-2. This C120 circuit breaker complies with both the domestic standard EN/IEC 60898-1 and the industrial standard EN/IEC 60947-2.

This circuit breaker protects the power circuits against short circuits and overload currents. The off position of the switch on the front is clarified with a green strip, making it easy to locate at a glance. This breaker has a good overvoltage capability and is designed to deliver high-performance with a long lifespan.

This Schneider Electric circuit breaker has an electrical life of up to 5000 cycles and a mechanical life of up to 20000 cycles. The Ui assigned insulation voltage is 500VAC according to EN/IEC 60947-2. The network frequency is 50Hz or 60Hz. The energy limitation class is 3 (according to EN/IEC60898-1), which contributes to cost-effective protection of the power circuit.

The circuit breaker can be mounted on a DIN rail for a modular installation. The width of this breaker is 6 modules of 18mm. The pollution degree is 3 and the overvoltage category is IV. This product is executed in white color (RAL9003). The dimensions are 108mm (W) x 81mm (H) x 73mm (D). The weight is 820g. According to the IEC 60529 standard, the protection degree is IP20. The protection degree increases to IP40 when it is mounted in a modular housing with insulation class II. The operating temperature is between -25°C and 70°C. The storage temperature is between -40°C and 85°C.
