- 天盾- Basic description

M20D series power lightning arresters are mainly used for Class D protection of power distribution systems. They are used to protect electrical and electronic equipment from lightning electromagnetic pulse induced voltage, operating transients and resonance (<100µs) overvoltage. Power supply protection in electrical, electrical appliances, 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, timely tripping, etc., and the flame retardant level reaches V-0 level, which can prevent fires to the greatest extent and play a safety protection role.
