4.9 Based on 1181 reviews SPD Surge Protection Devices
Our surge protection devices (SPDs) protect your home or business from power surges. These units are fitted in consumer units and distribution boards to stop damage from voltage spikes.
We stock both Type 1 and Type 2 SPDs for single-phase and three-phase systems. Type 1 devices handle direct lightning strikes, while Type 2 SPDs protect against switching surges and smaller spikes.
All surge protection units meet UK wiring standards and are quick to install. Whether you’re fitting a new board or upgrading an existing one, our SPDs help keep your circuits safe.
