The FuseBox surge protection metal consumer units feature 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. As with all of the FuseBox boards, the F2014MX has ample space for the installation of both standard height and mini RCBOs.
