Fuses

Fuses are protective devices containing a calibrated element that melts and breaks the circuit when current exceeds a safe level. Our range covers Deta plug top fuses from 2A to 13A, Lawson consumer unit fuses for older cartridge boards, Lawson 80A house service fuses, 63A Neozed D02 fuses and Lucy Zodion Titan single fuse cut-outs.

Trade pricing comes with a Meteor account, and in-stock fuses ordered before 5pm Monday to Friday can be on site the next working day anywhere in NI and the Republic.

Finding the right fuse

Fuses come in many shapes and sizes, and the correct replacement is always the same type and rating as the original unless the circuit design changes. Start by identifying where the fuse is used.

Fuse categories

Plug top fuses - small cartridge fuses fitted in 13A plugs and fused connection units.
Consumer unit fuses - cartridge fuses for older fuse boards that pre-date circuit breakers.
Cut-out fuses - house service fuses and single fuse cut-outs at the supply intake or in street furniture.
Neozed fuses - screw-in D type fuse links used in Neozed switch fuses.

What to check

Match the physical size, the current rating and the fuse characteristic. A fuse that looks similar can have a different breaking capacity or speed of operation, so read the markings on the original before ordering. For plug top fuses, the rating should suit the appliance and its flex, following the manufacturer's guidance.

Safety advice

Never replace a blown fuse with a higher rating or bypass it, as this removes the protection for the cable. Isolate the supply before changing any fuse that is not in a plug, and investigate the cause if a fuse blows repeatedly. Service fuses at the supply intake are normally the responsibility of the network operator. When older fuse boards are being replaced, current wiring regulations generally lead to a modern consumer unit with MCBs, RCDs or RCBOs.

FAQ's Ask Your Own Question

What is a fuse?: A fuse is a piece of wire made of a substance with a very low melting point. When a strong current travels across a circuit owing to overloading or a short circuit, the wires become hot and melt.
What are fuses used for?: If a failure in an appliance causes too much current to flow, the fuse trips the circuit. If something goes wrong, this safeguard both the wire and the appliance.
How do I know if a fuse has blown?: When a fuse breaks, the power to a certain circuit is instantaneously cut off. This reduces the chance of a fire and protects the wiring.
When should fuses be used?: Fuses are essential components of any electrical system because they protect the cabling of a circuit from excessive current, which can cause damage to the appliance and cause an electrical fire.
How often should I replace a fuse?: Fuses do not need to be replaced unless they have blown, thus it is not something that should be done on a regular basis.
How long do fuses last?: Fuses have a long life expectancy; fuses can last up to 20-30 years.
How do I identify which replacement fuse I need?: Read the markings on the existing fuse, which usually show the current rating, size, type code and sometimes the standard it meets. Then match where it is fitted, such as a plug, older consumer unit, service cut-out or Neozed holder. If the markings are unreadable, check the equipment manual or ask a qualified electrician.
Can I replace a fuse with a higher rated one?: No, a fuse should always be replaced with one of the same rating and type unless a competent person has redesigned the circuit. A higher rated fuse may allow the cable or appliance flex to overheat before it blows, creating a fire risk. If the correct fuse keeps failing, investigate the fault.
Are fuses or circuit breakers better?: Both protect against overcurrent, but circuit breakers can be reset after a trip and are easier for users to restore safely, which is why modern consumer units use MCBs and RCBOs. Fuses remain widely used in plugs, service cut-outs and industrial switchgear, where their high breaking capacity and simplicity are valuable.
