Handle type porcelain kit kat fuse unit, 415V, 32A to 200A — rewireable carrier with a pull handle and a matching base, one unit per phase.
- Porcelain kit kat fuse unit for 415 V circuits — pull-out carrier and base.
- Handle type: the carrier has a moulded handle for a firm grip when pulling it out.
- Four sizes: 32A, 63A, 100A and 200A.
- Rating and voltage embossed on the carrier (for example 63A AC, 415/500 V).
- Rewireable: fuse wire fits between the carrier contacts and melts on overload or short circuit.
- Porcelain (ceramic) base and carrier — non-combustible and heat-resistant, the traditional material for fuse units.
- Single pole — use one unit in each phase, three for a three-phase supply.
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 handle type range is for 415 V circuits, from 32A for motors, pumps and sub-circuits up to 200A for main switches and feeders; the moulded handle gives a firm grip on the carrier. The rating is the unit maximum — the fuse wire fitted sets the actual protection and must suit the cable and the load.
Which size do I need
- 32A — smaller three-phase motors and pumps, and sub-circuits.
- 63A — larger motors, machines and sub-distribution feeders.
- 100A — main switches of shops, workshops and small industries.
- 200A — main incomers and feeders of larger buildings and panels.
Typical uses only — the rating must always suit the cable and the load.
Where to use it
- Motor, pump and machine circuits in workshops, factories and farms.
- Main switches and feeders of shops, offices and apartment blocks.
- Replacing worn or cracked handle type units in existing boards.
How to install
- Switch off and isolate the supply, and confirm the circuit is dead.
- Fix the base on the board and connect the incoming and outgoing wires to its terminals.
- Fit fuse wire of the correct size in the carrier and tighten the screws.
- Push the carrier fully into the base; fit one unit in each phase.
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
- Excel or handle type — what is the difference?
- Both are porcelain rewireable fuse units for 415 V, made in different patterns of carrier and base; the handle type carrier has a moulded pull handle. A carrier generally fits only its own pattern and size of base, so match what is on your board or replace both parts.
- How many units do I need for a three-phase supply?
- Three — one in each phase. Each unit is single pole; the neutral goes through a link, never a fuse.
- What fuse wire should I use?
- Wire sized for the protection the circuit needs — never above the unit rating or what the cable can carry; thinner wire blows at a lower current. The 32A carrier pictured is marked MAX WITH 21 SWG. Never fit thicker wire or copper strands.
- Can I pull out the carrier with the supply on?
- No. Switch off the main switch or upstream isolator first — pulling a carrier on load can draw an arc that burns the contacts and the hand holding it.
- 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.
