Schneider Electric Circuit Breaker – A9F75420

This Acti9 iC60N is a low voltage circuit breaker. It is a 4P circuit breaker with 4 protected poles. It has a nominal current of 20A and a D disconnect characteristic. The interrupting capacity of this circuit breaker is 6000A at 400VAC according to the EN/IEC 60898-1 standard (domestic standard) and 20kA at 220VAC to 240VAC according to the EN/IEC 60947-2 standard (industrial standard).

This iC60N 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 from short-circuits and overload currents. The unique VisiTrip indicator shortens the search for the tripped circuit breaker by clearly marking it. The green indication of VisiSafe guarantees the physical opening of the contacts, so maintenance downstream can be performed. The rapid disconnect mechanism extends the life of this component.

This Schneider Electric circuit breaker has an electrical lifespan of up to 10,000 cycles and a mechanical lifespan of up to 20,000 cycles. The Ui assigned insulation voltage is 500VAC. Its limitation class 3 (according to EN/IEC60898-1) reduces the cost of protecting the power circuit. It can be mounted on a DIN rail for a modular installation. The width of this circuit breaker is 4 modules of 18mm. The pollution degree is 3 and the overvoltage category is IV.

This product is finished in white color (RAL9003). The dimensions are 72mm (W) x 85mm (H) x 78.5mm (D). The weight is 0.5kg. According to the IEC 60529 standard, the degree of protection is IP20. The protection degree goes up to IP40 when it is mounted in a modular housing with insulation class II. The operating temperature is between -35°C and 70°C. The storage temperature is between -40°C and 85°C.
