Schneider Electric Circuit Breaker – A9F78440

This text describes the Acti9 iC60N, a low voltage circuit breaker. This is a 4P circuit breaker with 4 protected poles. It has a nominal current of 40A and a B tripping characteristic. The breaking 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).

The iC60N circuit breaker complies with both the domestic EN/IEC 60898-1 standard and the industrial EN/IEC 60947-2 standard. This circuit breaker protects the power circuits against short circuit and overload currents. The unique VisiTrip indicator shortens the search for the tripped circuit breaker by clearly marking it. The green VisiSafe indication guarantees the physical opening of the contacts, allowing downstream maintenance to be carried out. The quick breaking mechanism extends the life of this component.

This Schneider Electric circuit breaker has an electrical life of up to 10,000 cycles and a mechanical life of up to 20,000 cycles. The Ui rated insulation voltage is 500VAC. Its limitation class 3 (according to EN/IEC60898-1) reduces the costs 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 white (RAL9003) in color. The dimensions are 72mm (W) x 85mm (H) x 78.5mm (D). The weight is 0.5kg. According to the IEC 60529 standard, the protection degree is IP20. The protection degree increases to IP40 when mounted in a modular enclosure with insulation class II.

The operating temperature is between -35°C and 70°C. The storage temperature is between -40°C and 85°C.
