Description

Surge protection device(SPD) is an indispensable device for lightning protection of electronic equipment. It is used to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or A powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.  

Main structure and working principle

  • SPD is a port, anti-stock protection, indoor fixed installation, voltage limited type.
  • SPD built-in disconnector. When the SPD fails due to overheating and breakdown, the disconnector can automatically detach its grid and given an indication signal.
  • When the SPD is woking normally, the visible window displays green, and when the failure is detached, it displays red.
  • 1P+N,2P+N,3P+N consists of 1P, 2P,3P SPD+NPE zero ground protection module, applied to TT, TN-S and other power supply systems.
