Fuse Switches for Submains and Local Isolation

Fuse switches provide a practical way to isolate and protect a circuit using a switch mechanism and fuse protection in one unit. They are often used where power needs to be supplied from a main installation to a separate area, item of equipment or smaller distribution point.

Common applications include garage supplies, garden rooms, workshops, sheds, commercial equipment, plant supplies and small distribution circuits. The correct fuse switch should always be selected based on the load, supply type, cable size, fault protection requirements and installation environment.

Choosing the Right Fuse Switch

When choosing a fuse switch, check the current rating, number of poles, enclosure type, fuse compatibility and whether the product is suitable for the intended location. Some installations may require a metal enclosure, a three-phase unit or a switch fuse suitable for a specific supply arrangement.

  • Check the required current rating for the circuit.
  • Confirm whether single-phase or three-phase protection is required.
  • Choose a suitable enclosure for indoor or protected locations.
  • Confirm the correct fuse type and rating.
  • Check cable entry, mounting space and installation requirements.

Fuse Switches and Consumer Units

Fuse switches are often used as part of wider circuit protection and distribution board installations. If you are also choosing a board for the installation, browse our main consumer units category and always check compatibility with the circuit design, protective devices and manufacturer instructions.

Installation Notes

Fuse switches should be selected, installed and tested by a qualified electrician in accordance with current UK wiring regulations and the manufacturer’s instructions. The installer should confirm the correct fuse rating, cable size, earthing arrangement, enclosure suitability and isolation requirements before installation.

Fuse Switches FAQs

What is a fuse switch used for?

A fuse switch is used to provide isolation and fuse protection for a circuit or item of equipment. It allows the circuit to be switched off while also providing protection through a suitable fuse.

Are fuse switches used for garage or shed supplies?

Fuse switches are commonly used for submains and supplies to garages, sheds, workshops and outbuildings, where suitable for the installation design.

What is the difference between a fuse switch and an isolator?

An isolator provides switching and isolation only. A fuse switch provides isolation and includes fuse protection, where required by the circuit design.

Who should install a fuse switch?

A fuse switch should be installed by a qualified electrician who can confirm the correct rating, fuse type, cable size and installation requirements.
