7KA Lightning arrester Type 1+2 SPD Ac Surge Protection Description:
Surge protection devices are designed to protect electrical equipment from surge voltage. They limit transient overvoltage, divert current impulses to the ground and reduce the overvoltage amplitude to a level that is safe for electrical installations and equipment. SPDs are used both in Civil Construction and in Industrial facilities.
