White 80kA Power Surge Protection Device 3 Phase 4P 385V ISO9001 Certificated

Second level of protection
The purpose is to further limit the value of the residual surge voltage through the first level of lightning protection to 1500-2000V, the LPZ1-LPZ2 implementation of the equipotential connection.
Sub-distribution cabinet line output power supply lightning arrester as the second level of protection should be voltage limiting power supply lightning arrester, its lightning current capacity should not be less than 20KA, should be installed in the power supply to important or sensitive power equipment at the branch distribution. These power supply lightning protector for the user through the power supply entrance surge discharger residual surge energy for better absorption, for transient overvoltage has an excellent suppression effect. The use of the power supply lightning arrester requires the maximum impact capacity of 45kA per phase or more, the required limit voltage should be less than 1200V, called CLASS Ⅱ power supply lightning arrester. General users of the power supply system to achieve the second level of protection can reach the requirements of the operation of power-using equipment
