This Acti 9 iC60N is a low voltage miniature circuit breaker (MCB). It is a 4P circuit-breaker with 4 protected poles, 50A rated current and B tripping curve. It can be mounted on DIN rail for modular installation. As circuit-breaker, its breaking capacity, according to IEC/EN 60898-1, is 6000A at 400VAC. As circuit-breaker, its breaking capacity, according to IEC/EN 60947-2, is 20kA at 230VAC and 10kA at 400VAC. This miniature circuit breaker protects circuits against short circuit and overload currents. It has an IP20 degree of protection (as per IEC/EN 60529) on its terminals. It becomes IP40 once in modular enclosure with insulation class II. its fast closing mechanism improves its service life. Its limitation class 3 (according to EN/IEC60898-1) improves downstream circuit protection cost. 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.
