1.2/50 Type3 surge protective device Line detail protection

Product introduction

Surge protector is the lightning protection measures taken by Zhejiang tohr Electric Co., Ltd., which is independently developed and manufactured for electrical system. It is designed according to IEO and GB standards. It is applied to power supply protection of equipment system in areas with high lightning risk.
It can prevent all kinds of surge currents directly hitting lightning. It can be applied to single-phase and three-phase power supply lines and modular design through different combinations.

Working principle of product

When the surge protector has no voltage, the impedance is very high, which means that the circuit breaker is open. When the voltage occurs, the impedance drops to a few Europe, and the surge current will flow through the surge protector and will not enter the device. At the same time, because the surge protector has a small impedance at this time, the voltage on both sides of the surge is relatively small, and because he is in parallel with the protected equipment, it prevents the equipment from suffering from large surge power. Pressure, so as to play the effect of discharge and pressure limiting.
