Contactum Combines Compact Design with Full SPD Protection
Posted by: user_amy 3rd June 2026
Contactum are set to introduce their latest addition to circuit protection: the new Type 2 Compact Surge Protection Device (SPD) range, designed specifically for use with Defender 2.0 consumer units and Defender B Boards.
Developed to meet the evolving demands of modern electrical installations, the Compact SPD range delivers high-performance protection against transient overvoltages while addressing one of the industry’s key challenges – limited space within distribution boards. By significantly reducing the footprint of the SPD, the new design enables more efficient use of available space without compromising safety or performance.
This provides greater flexibility for installers, particularly in domestic environments where additional circuits and emerging technologies are increasingly being integrated into consumer units. In commercial and industrial settings, where system complexity and load demands are higher, the compact design supports more streamlined board layouts and the delivery of compliant, space-conscious systems.

Despite its reduced size, the Type 2 Compact SPD range has been engineered to deliver the same level of protection expected from traditional devices, ensuring installations remain fully safeguarded against transient overvoltages.
The launch aligns with recent updates in industry guidance, including BEAMA recommendations and manufacturers’ instructions, which clarify installation practices for SPDs in domestic applications. Under defined conditions, it is now permissible to omit a dedicated Miniature Circuit Breaker (MCB), with protection instead provided via the Distribution Network Operator fuse. Contactum’s Compact SPD for Defender 2.0 consumer units has been designed in line with this guidance, enabling a more streamlined configuration while maintaining full compliance and safety.
Alan Broom, Technical Manager at Contactum said: “The way electrical installations are designed is changing, with increasing pressure to maximise space without compromising safety. Our new Compact SPD range has been developed to meet that need, delivering trusted protection in a smaller format that supports faster installation and greater flexibility for both domestic and commercial applications.”
For Defender B Boards, the introduction of compact SPD solutions further supports efficient and reliable system design in commercial and industrial projects, where continuity of operation is critical.
As electrical systems continue to grow in complexity, the importance of reliable, standards-compliant protection remains paramount. The new Compact SPD range reflects Contactum’s ongoing commitment to delivering solutions that combine safety, performance and practicality for modern installations.
