Surge Protective Devices (SPDs) for Consumer Units & Distribution Boards

Protect electrical installations from transient overvoltages caused by lightning activity and switching surges with our range of Surge Protective Devices (SPDs). This category includes SPDs and kits suited to both domestic consumer units and commercial distribution boards, with options designed to meet BS 7671 expectations.

 

Type 1, Type 2 & Combined Type 1+2 Surge Protection

Choose Type 1 SPDs for installations where direct lightning currents may be present at the origin, Type 2 SPDs for protection against switching and residual surges, and combined Type 1+2 devices commonly used in consumer units. Where multiple devices are used, they should be properly coordinated for correct operation.

 

Single Phase, Three Phase & Solar PV DC SPDs

Shop by application with dedicated ranges for Consumer Unit SPDs, Single Phase SPDs, Three Phase SPDs, and SPD Surge Protection for Solar PV. You’ll also find practical all-in-one options such as SPD kits, stand-alone enclosures, and meter supply isolators with surge protection.

 

Filter by Earthing System, Poles, IP Rating & Features

Use the filters to match your install quickly — including SPDs for TN-S, TN-C-S, TT, and IT systems, plus choices by number of poles (1P/2P/3P/4P), IP rating (e.g. IP20/IP55), and extras like LED indication, data/telephone protection, and enclosure options.

Choose from well-known names including FuseBox, Hager, Live Electrical, Niglon, WCED, and specialist ranges such as Citel options for DC applications.
