Model： UT-M4-40C
AC power surge protectors are mainly used for C-level protection of power distribution systems. They are used to protect electrical and electronic equipment from lightning electromagnetic pulse induced voltages, operating transients and resonance (<100μs) overvoltage. They are widely used in communication equipment, electrical appliances, power equipment, security monitoring, transportation, industrial control, aviation and other fields of power protection. This series of products has the characteristics of extremely fast response time, built-in thermal protection, low residual voltage, timely tripping, etc., and the flame retardant level reaches V-0 level, which can prevent fires to the greatest extent and play a role of safety protection.
