3.3kva Dual Outlet 110v Transformer

The 3.3KVA dual outlet 110V transformer is a workhorse piece of kit for anyone running power tools on a construction site. It takes your standard 230V mains supply via a BS-approved 13A plug and steps it down to 110V, which is the required standard for site tools across the UK. Two 16A sockets mean you can run a couple of tools at the same time without swapping leads around or carrying two transformers to site.

The casing is a heavy-duty GPR (glass-reinforced polyester) construction, fully weatherproof and rated to IP44. That means it can sit out on a wet slab or in a damp outbuilding without you losing sleep over it. It is not designed for full submersion, but it handles the usual site conditions without complaint. There is a blue LED power indicator on the front so you can tell at a glance whether the unit is live. Simple idea, genuinely useful when you are working in poor light or across a busy site.

Thermal Protection on the 3.3KVA Dual Outlet 110V Transformer

One of the more practical features here is the resettable thermal overload protection. If the unit trips due to overloading or overheating, you do not need a replacement fuse or a call to the hire shop. Press the reset button and you are back up. This happens more often than people expect, particularly when running two heavy-draw tools at the same time.

The continuous rating is 1.8KVA, which covers a single mid-range tool comfortably. The 3.3KVA peak capacity gives you headroom for startup surges when running two tools. Worth bearing that in mind when choosing what you plug in. A large angle grinder and a heavy drill pulling simultaneously will push it harder than two smaller tools.

Priced at under £70, this transformer undercuts most hire costs over a few weeks. If you are on a longer job or buying for regular use, it pays for itself quickly. Supplied ready to use straight out of the box.
