With exquisite craftsmanship, it can work for a long time in high humidity and harsh environments

Product Details

basic descriptionBasic description-Heavenly Shield-

The M40B series products are mainly used for C-level protection in power distribution systems, to protect electrical and electronic equipment from the effects of lightning electromagnetic pulse induced voltage, transient operation, and harmonic (<100 µ s) overvoltage. They are widely used in power protection in communication equipment, electrical, electrical, power equipment, security monitoring, transportation, industrial control, aviation and other fields. This series of products has the characteristics of particularly fast response time, low residual pressure, and timely tripping, and the flame retardant level reaches V-0 level, which maximizes the prevention of fires and plays a role in safety protection.
