16A 240V porcelain kit kat fuse unit — rewireable carrier and base for single-phase circuits, with the rating embossed on the carrier.
- Porcelain kit kat fuse unit — base and pull-out carrier — for single-phase circuits.
- Rated 16A, 240 V, embossed on the carrier.
- Rewireable: fuse wire fits between the screw contacts of the carrier and melts on overload or short circuit.
- Screw terminals in the base for the incoming and outgoing wires.
- Fixing hole in the centre of the base for screw mounting.
- Porcelain (ceramic) base and carrier — non-combustible and heat-resistant, the traditional material for fuse units.
- Fit it in the phase wire only — never in the neutral.
A porcelain kit kat fuse unit has two parts: a base, fixed on the board and wired into the circuit, and a carrier that holds the fuse wire and plugs into the base. On an overload or short circuit the wire melts and breaks the supply; you switch off, pull out the carrier, refit wire of the correct size and push it back.
This 16A, 240 V size is for single-phase circuits — a sub-circuit, a pump or machine supply, or an older main board. For 415 V and higher currents, see our Excel and handle type units (32A to 200A) and the 300A and 500A units with strip.
Protection depends entirely on the fuse wire: fit wire rated for the circuit, never above 16A, and never thicker wire or copper strands. An MCB does the same job and resets with a switch; neither protects against electric shock, which needs an RCCB.
Where to use it
- Single-phase sub-circuits in older homes, shops and godowns.
- Pump, motor and machine supply boards that use rewireable fuses.
- Replacing a worn or cracked 16A kit kat on an existing board.
How to install
- Switch off the main supply and confirm the circuit is dead.
- Fix the base on the board through its centre hole.
- Connect the incoming phase and the outgoing phase (to the load) to the base terminals — phase conductor only.
- Fit fuse wire of the correct rating across the carrier contacts, tighten the screws and push the carrier home.
Electrical work should be done by a licensed electrician. Never pull out or push in a fuse carrier on load — switch off the supply first.
Frequently asked questions
- What is a kit kat fuse unit?
- A rewireable fuse in two parts: a base wired into the circuit and a pull-out carrier that holds the fuse wire. When the wire melts on an overload or short circuit, you switch off, rewire the carrier and push it back.
- What does 16A 240V on the carrier mean?
- The unit is made for single-phase circuits of up to 16 amperes. The fuse wire you fit sets the actual protection — choose it for the load and the cable, never above 16A.
- Can I use it on a 415 V three-phase circuit?
- No — it is marked 240 V. Use our 415 V Excel or handle type units instead.
- Why does my fuse keep blowing?
- Too much load on the circuit, a faulty appliance or motor, or a wiring fault. Switch off and have the circuit checked — fitting thicker wire only hides the fault and can start a fire.
- Kit kat fuse or MCB — which should I choose?
- An MCB trips more precisely and resets with a switch — the modern choice for distribution boards. A rewireable fuse is simple and economical and still common in motor, pump and older main-switch boards, but it protects only with the correct fuse wire.
- Does a fuse protect against electric shock?
- No. A fuse acts on overload and short circuit only. Protection against shock from earth leakage needs an RCCB of 30 mA or less.
