Multi 9 – C60SP – MCB – 4P – 50 A – D Curve – 480Y/277 V – 5 kA – UL 1077

This Multi 9 C60SP is a low voltage miniature circuit breaker (MCB). It is a 4P circuit-breaker with 4 protected poles, 50A rated current and D tripping curve. It can be mounted on DIN rail for modular installation. As circuit-breaker, its breaking capacity, according to IEC/EN 60947-2, is 20kA at 230VAC and 10kA at 400VAC. This circuit-breaker offers a supplementary protection of circuits against short circuit and overcurrent (UL 1077). It has an IP20 degree of protection (as per IEC/EN 60529) on its terminals. It becomes IP40 once in modular enclosure. The tripping or fault indication functions are remotely provided by adding electrical auxiliaries. The green mechanical indication guarantees the physical opening of the contacts to allow downstream maintenance.
