Schneider Electric Circuit Breaker – A9F78250

This Acti9 iC60N is a low-voltage circuit breaker. It is a 2P circuit breaker with 2 protected poles. It has a nominal current of 50A and a B cut-off characteristic. The switching capacity of this circuit breaker is 6000A at 400VAC according to the standard EN/IEC 60898-1 (domestic standard) and 20kA at 220VAC to 240VAC according to the standard EN/IEC 60947-2 (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 electrical circuits against short-circuiting and overload currents. The unique VisiTrip indicator shortens the hunt for the shut-off (tripped) circuit breaker by clearly marking it. The green display of VisiSafe guarantees the physical opening of the contacts, so that the maintenance can be performed downstream. The fast switching mechanism extends the life of this component.

This Schneider Electric circuit breaker has an electrical life up to 10000 cycles and a mechanical life up to 20000 cycles. The Ui assigned insulation voltage is 500VAC. Its restriction class 3 (according to EN/IEC60898-1) reduces the costs for protecting the power circuit. It can be mounted on a DIN-rail for a modular installation. The width of this circuit breaker is 2 modules of 18mm. The pollution degree is 3 and the overvoltage category is IV.

This product comes in the color white (RAL9003). The dimensions are 36mm (W) x 85mm (H) x 78.5mm (D). The weight is 0.25kg. According to the standard IEC 60529, the degree of protection is IP20. The degree of protection 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.
