Application

ZAS1 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. 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 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.

1.Single-pole product, used for protecting 220V single-phase system against the surge over voltage.

2.Two-pole combined product, used for protecting 220V single-phase system against  and N-to-earth lightning over voltage.

3.Three-pole combined protect, used for protecting 380V TT and TN-S system against L-to-L lightning over voltage and for protecting 380V IT and TN-C systems against S-to-S lightning over voltage.

4.Four-pole combined product, used for protecting 380V TT and TN-S systems against L and N-to-earth lightning over voltage.
