Description
The Mercury 4-way plug-in mains adaptor converts a single 13A UK wall socket into four individually switched outlets, each with its own colour-coded rocker switch and neon ON/OFF indicator. The unit plugs directly into a standard UK 3-pin socket without requiring a trailing cable, keeping the installation compact and the floor clear of extension leads.
Designed for kitchens, home offices, and workshop benches where multiple appliances or chargers need access to a single socket, the adaptor supports a combined maximum load of 3000W (13A at 230V) across all four outlets. Each socket can be independently switched off when not in use, reducing standby power draw and allowing selective control of connected devices. The built-in 13A fuse provides overload protection, while the unit complies with BS1363/A and BS5733/A standards for UK electrical accessories.
The white thermoplastic housing measures 218mm wide by 112mm tall with a 33mm depth from the wall when plugged in, making it lower-profile than many multi-socket extensions. The four colour-coded switches (purple, blue, red, green) provide clear visual differentiation when multiple devices are connected, reducing the chance of switching off the wrong appliance. The unit weighs 228g, light enough not to strain older or looser wall sockets.

Frequently Asked
What is the maximum combined load across all four sockets?
The adaptor supports a maximum of 3000W or 13A at 230V across all four outlets combined. This means if one socket is drawing 10A, the remaining three can collectively draw up to 3A before reaching the fuse limit.
Does each socket have its own fuse?
No. The adaptor has a single 13A fuse that protects all four outlets. Each socket does have its own rocker switch with a neon indicator, allowing individual outlets to be switched off independently.
Will the adaptor fit in a recessed socket?
The 33mm depth from the wall may prevent the adaptor from fitting flush if the wall socket is recessed significantly below the plaster line. It works best with flush-mounted or surface-mounted sockets.
Does it include surge protection?
The unit includes basic surge and spike protection as stated in the original product description, providing a level of safety for connected electronics. However, for sensitive equipment like computers or audio systems, a dedicated surge-protected extension lead may offer additional protection.
