Mastertrade is excited to announce the latest innovation from FuseBox—the all-new F3 Series consumer units, now featuring a cutting-edge single-module Type 2 Surge Protection Device (SPD). This new SPD model, the SP1MT2, connects directly to the busbar without requiring an additional miniature circuit breaker (MCB). This clever design significantly reduces the space needed inside the consumer unit, providing electricians with an extra usable way within the board and simplifying the overall installation process.
The FuseBox F3 Series is designed to meet the diverse needs of modern electrical installations. It offers a broad selection of configurations ranging from compact 4-way units up to extensive 48-way options. These are available in Single Bank, Double Bank, and Triple Bank designs, ensuring flexibility for both simple and complex wiring setups.
