Product Description
Surge Protective Devices Surge Protection Application EBS9U Surge protective devices ( referred as SPD) provide protection against surge current resulted from direct or indirect lightning strike or similar surge voltage. SPD is applicable to circuit with rated voltage up to 400V~, rated frequency 50/60Hz. The product, using metal oxide varistor, designed to protect both phase and neutral line, is of high electricity resistance under normal operation. In case of surge current or voltage caused by lightning strike or similar, SPD functions quickly to conduct the surge voltage/current to earth and thus effectively prevent the downstream equipment of its protected line from destruction. SPD resume its high electricity resistance to secure normal operation of the protected power network without presence of the surge voltage.
