Main Switches: Where the Whole Installation Isolates

The device at the top of every board: FuseBox main switches run the 100A double pole through 100A and 125A 4 pole AC22A units and a 125A 3 pole with unswitched neutral, Click Essentials fused main switches carry 80A and 100A bodies with 80A HRC fuses fitted, and FuseBox’s Mini AFDD devices pair arc fault detection with a Type A 30mA RCBO at 6A to 32A, protection the main switch era never had.

Frequently Asked Questions

Total isolation: it disconnects every circuit in the board with one action, the first requirement of safe work on any installation.

The sub-main feed: the Click units combine isolation with an 80A HRC fuse, protecting the cable to an outbuilding or annex board.

Three phase convention: the 125A 3P+N unit switches the phases while the neutral runs solid, per the installation design.

Arc detection: the Mini devices spot the signature of arcing faults, the fire-starters that trip neither MCB nor RCD, alongside 30mA Type A protection.

The regulation’s targets: socket circuits in higher risk residential buildings first, and anywhere arc risk concentrates.

The switching duty: the utilisation category rating for switching mixed resistive and inductive loads on the 4 pole units.
