SPA103 Datasheet (Click here to open)

The SPA103 is for installation at LPZ0_B-1 or higher, protecting low voltage equipment from surge damage.

This surge protection device has a pluggable modular SPD Class 2 (Class C) for TT and TN-S power supply system.

The SPA103 is usually installed in the distribution-box or feeder bus of the UPS, protecting devices or equipment downstream.

A fuse must be installed at the upstream of the SPD/lightning arrester to ensure that the protected system has double protection.
