C120N – automatski prekidač – 1P – 125A – B kriva

Acti 9 C120N is a low voltage miniature circuit breaker (MCB). It is a 1P circuit-breaker with 1 protected pole, 125A 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 10000A at 230VAC and 400VAC. As circuit-breaker, its breaking capacity, according to IEC/EN 60947-2, is 10kA at 230VAC and 3kA 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. That becomes IP40 once in modular enclosure. its fast closing mechanism improves its service life. Its limitation class 3 (according to EN/IEC60898-1) improves downstream circuit protection cost. The tripping or position indication functions are remotely provided by adding electrical auxiliaries. Its Visisafe green strip guarantees the physical opening of the contacts to allow downstream maintenance..
