DC miniature circuit breakers (DC MCBs) provide overload and short-circuit protection in direct current electrical systems including solar PV arrays, battery energy storage systems, EV charging infrastructure, telecommunications power supplies, and industrial DC drive panels. Unlike standard AC MCBs, DC MCBs are specifically engineered to interrupt DC arc faults — which are more persistent than AC arcs due to the absence of a natural current zero-crossing. GoSwitchgear stocks DC MCBs in 1-pole, 2-pole, and 4-pole configurations from 1A to 63A, rated for 250V DC and 500V DC (1000V DC for solar series), complying with IEC 60947-2.
