A surge protector contains metal oxide varistor, or MOV, which diverts any extra voltage to ensure devices receive a consistent power level. The MOV works like a pressure-sensitive valve. When the MOV detects high voltage levels, it reduces resistance. If voltage levels are too low, it increases resistance

FPV-63 DC MCB supplementary protectors are designed to provide overcurrent protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications.
