Multi 9 – C60H-DC – MCB – 2P – 40 A – B Curve – 500 V DC – 10 kA

This Multi 9 C60H-DC is a low voltage miniature circuit breaker (MCB) dedicated to direct current. It is a 2P circuit-breaker with 2 protected poles, 40A 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 60947-2, is 20kA at 220VDC and 10kA at 440VDC. 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.
