FuseBox Type 2 surge protection device T2 for TN Systems. Compact 1 modular width version that comes with a 32A MCB and connecting cable.

  • Features

    The FuseBox Type 2 Surge Protection Device (SPD) is designed to be a robust and efficient solution for protecting electrical systems from surge damage, particularly in TN systems. Its compact design, measuring just 1 module in width, makes it an ideal choice for installations where space is at a premium.

    The inclusion of a 32A B Type Miniature Circuit Breaker (MCB) enhances the protective capabilities of this SPD, ensuring that both the SPD and the electrical system it serves are safeguarded against overcurrent conditions. The device's easy-fit MCB form factor further simplifies installation, making it a convenient option for both new builds and retrofit projects.

    Furthermore, this SPD kit boasts a terminal capacity of up to 16mm2, accommodating a wide range of cable sizes for versatile application. The device comes complete with installation instructions and a device sticker to assist with proper installation and maintenance. The presence of a flag indicator provides a straightforward means of monitoring the device's status, with green signifying proper operation and red indicating the need for replacement. With nominal and maximum discharge currents rated at 20kA and 40kA respectively, this SPD offers substantial protection against electrical surges, supported by its Metal Oxide Varistor (MOV) technology. Its IP20 rating ensures protection against solid objects larger than 12.5mm, making it suitable for indoor installations. The FuseBox Type 2 SPD is a comprehensive solution designed to meet the demands of modern electrical installations, providing reliable surge protection with the added convenience of a compact form factor and easy installation.

    Hi can these be used on a tt system
    Question by: Matt thomas on 10 May 2022, 12:50

    Thanks for your question. I've double checked this with FuseBox:

    SPDCUKITT2 are suitable on TT systems only if fed from an underground power source.

    TT systems which are fed from overhead power cables require a Type 1 SPD, for direct protection from lightning strikes.

    FuseBox have a new Type 1 SPD (SPDCUKITT1) which is expected to be in stock from July.
