    FuseBox surge protection metal consumer units with a 100A rated MS (Main Switch) incomer and T2 SPD (Surge Protection Device). Surge protection consumer units provide formidable circuit protection against surge and overload. When fitted with additional RCBOs (Residual Current Circuit Breaker with Overload Protection) as an outgoing device, you also get residual current protection.

    Available in 7 frame sizes ranging from 6 to 44 useable ways. FuseBox surge protected consumer units now come with an additional MCB that protects the SPD. This MCB takes up one of the useable ways but the SPD is now single pole, giving you an additional useable way.

    They require additional outgoing devices such as MCBs (Miniature Circuit Breakers) or RCBOs. RCBOs are available in Type AC and Type A versions.

    Metal consumer units from FuseBox are constructed from steel and are 18th Edition compliant. Now available in large triple row sizes with up to 44 useable ways.

    Can these units be mounted on there side ?
    Question by: David Wren on 5 May 2022, 14:37
    FuseBox have said they don't recommend side mounting.

    What is the warranty

    Who sells your product in N. Ireland
    Question by: Mark O'Sullivan on 17 Aug 2022, 16:28
    The warranty is 1 year, but they never fail. FuseBox are a very reliable and popular brand.

    We can deliver to N. Ireland and delivery is free on orders over £150 or £7 if below.
    Answer by: Chris Horridge (Admin) on 18 Aug 2022, 07:23

    I install several CUs per month. Yours looks a decent model and I can see a unique design feature that I particularly like, However, Type 2 SPDs are not permissible for TT Systems or supplies via overhead lines. This applies to a lot of housing stock. Such systems require Type 1 SPDs. Do you produce boards to accommodate Type 1 SPDs and what are the price ranges?

    Question by: Robert Davies on 2 Aug 2023, 11:22

    Very good question, I've checked this with FuseBox and we 2 solutions:

    You can install SPDCUKITT1 into an F2015M (15 way example with main switch)


    Main switch consumer units:

    As SPDUCKITT1 is 3 modules (2 for the type 1 SPD and 1 for the MCB), the main switch would need to be moved to the left, meaning the tail clamp will not line-up.

    Therefore, all that is required is that the main switch needs to be moved to the LHS by 18mm, busbar shortened by 18mm, and tail clamp would need to be removed or a new hole drilled and taped to secure it.

    Alternatively, although we do not offer consumer units fitted with Type 1 SPD as standard, we can provide these if required.

    Please let us know if this is something you would like to order & I can request pricing for you.
