Description

SPD9-D (E) series surge protective devices suitable for TT,IT,IT-S,TN-S,TN-C,TN-C-S etc. power supply system of AC 50/60Hz,≤230/400V,which protects the electric network not shocked by the thunder and releases 100kA over current. It’s designed according to IEC61643-1, GB18802.1, GB50057, and usually installed in the building of low-voltage main power distribution cabinet.

Features

1. Module design, easy installation, electrified maintenance easy operation.

2. Built-in over current and over heat, temperature control circuit breaking technology.

3. Quick response less than 25ns.

4. Alarm display, green(normal), red (malfunction).

Installation guide

This SPD is used in the equal potential connection in case of surge current caused by lightning strike or similar and it’s installed in the junction area of LPZOA or LPZ1.
