DC MCB (DC miniature circuit breaker) plays a key role in the power system.
AC Surge Protective Device is an indispensable device for lightning protection of electronic equipment. Its main function is to limit the transient overvoltage that penetrates into power lines and signal transmission lines to the voltage range that the equipment or system can withstand, or to release strong lightning current to the ground, thereby protecting the protected equipment or system from damage .
A DC Surge Protective Device is a crucial component in electrical systems designed to safeguard against potentially damaging surges or transients in direct current (DC) lines. These devices, often referred to as surge arresters or surge suppressors, play a vital role in protecting sensitive electronic equipment from the effects of electrical disturbances.
