This Multi 9 C60 UL1077 is a low voltage miniature circuit breaker (MCB). It is a 2P circuit-breaker with 2 protected poles, 10A rated current and C 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 10kA at 230VAC and 400VAC. This circuit-breaker offers a supplementary protection of circuits against overload currents according to 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 trip-free mechanism allows the contacts to not be held in the on position when the device is tripped automatically. The green mechanical indication guarantees the physical opening of the contacts to allow downstream maintenance.
