NP1-63DC Miniature Circuit Breaker (DC MCB) is specially designed for photovoltaic DC distribution systems requiring reliable protection at high operating voltages. Rated for working voltages of up to 1000V DC, it provides effective protection against overloads and short-circuit faults in solar power installations.

The breaker features a dedicated DC arc-extinguishing and current-limiting system, enabling rapid interruption of fault currents. This helps protect PV modules, DC strings, and inverters from damage caused by reverse currents or AC feedback resulting from inverter failure.

Ideal for PV combiner boxes, string protection, rooftop and utility-scale solar plants, the NP1-63DC ensures safe, stable, and long-term operation of photovoltaic power generation systems.
