Surge protective devices (referred as SPD) provide protection against surge current resulted from direct or indirect lightning strike or similar surge voltage.
SPD2 Type 230V/400V 20ka SPD Surge Protective Device
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 operations. ln 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 equipments 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.
