Schneider A9F77432 | Miniature circuit-breaker, Acti9 iC60N, 4P, 32 A, C curve, 6000 A (IEC 60898-1), 10 kA (IEC 60947-2)

Schneider A9F77432 Description

This Acti9 iC60N is a low voltage miniature circuit breaker (MCB). It is a 4P circuit breaker with 4 protected poles, 32A rated current and C tripping curve. The rated short circuit breaking capacity goes up to 20kA at 220VAC to 240VAC conforming to EN/IEC 60947-2 standard and 6000A at 400VAC conforming to EN/IEC 60898-1 standard.

It complies with both industrial standard EN/IEC 60898-1 and residential standard EN/IEC 60947-2. This miniature circuit breaker protects circuits against short circuit and overload current.

Its unique VisiTrip indicator reduces intervention time by showing the faulty circuit.

Its VisiSafe green strip guarantees the physical opening of the contacts to allow downstream maintenance. Its fast-closing mechanism independent of manual operation improves its service life.

It has an electrical endurance going up to 10000 cycles and a mechanical endurance going up to 20000 cycles. The Ui rated insulation voltage is 500VAC. Its limitation class 3 (according to EN/IEC60898-1) improves downstream circuit protection cost.

The product can be clipped on a DIN rail. Its width is 8 pitches of 9mm. Pollution degree is 3.

Overvoltage category is IV. The product colour is white (RAL9003).

The dimensions are (W) 72mm x (H) 85mm x (D) 78.5mm. The weight is 0.5kg. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is -35°C to 70°C. The storage temperature is -40°C to 85°C.
