Double pole (DP) tiny trip MCB, 6A to 32A — a modular mini MCB that fits a switch plate, C curve, 240 V AC, switching phase and neutral together.
- Mini MCB in modular switch form — 2 modules wide, it fits a modular switch plate and box.
- Switches phase and neutral together — the two handles are joined by a common bar.
- C curve (for example C-20 on the 20A unit) — rides through the starting surge of ACs and pumps.
- Rated 240 V AC, 50 Hz, for single-phase circuits.
- Trips on overload and short circuit and resets with the handle — no fuse to replace.
- I and O (on/off) marks and a D.P. terminal diagram (1–2, 3–4) on the front.
- Ratings 6A, 10A, 16A, 20A, 25A and 32A for AC, geyser, pump and appliance points.
A tiny trip MCB is a miniature circuit breaker made in the shape of a modular switch. It sits in the same plate and box as your switches and sockets, so an appliance point gets its own overload and short-circuit protection — and a proper on/off — right where the appliance is used. This double pole (DP) version switches phase and neutral, with its two handles joined so they always move together.
It is for per-point protection after the distribution board, not a replacement for the DB MCBs: plate-mounted mini MCBs generally have a lower breaking capacity than DIN-rail MCBs (ours are 10 kA). Like every MCB, it does not detect earth leakage — shock protection needs an RCCB.
Which rating do I need
- 6A — a light, fan or small-appliance point, on 1 or 1.5 sq mm cable.
- 10A — TV, computer and small-appliance points or a geyser up to 2 kW, on 1.5 sq mm.
- 16A — a power socket, a geyser up to 3 kW or a 1 to 1.5 ton AC, on 2.5 sq mm.
- 20A — a 1.5 to 2 ton AC or a small single-phase pump, on 2.5 or 4 sq mm.
- 25A — a 2 ton AC, an oven or induction cooktop, on 4 sq mm.
- 32A — a 4 to 6 kW water heater or oven, on 6 sq mm.
Typical values with copper cable — your electrician should match the MCB to the load and the cable.
Where to use it
- AC, geyser, water pump, washing machine and kitchen-appliance points.
- Replacing an old DP switch with one that also trips on overload and short circuit.
- Offices, shops and hotels — per-point protection for heavy appliances.
How to install
- Switch off the supply at the distribution board and confirm the point is dead.
- Connect the supply phase and neutral on one side and the appliance on the other, as per the diagram on the front, and tighten the terminals firmly.
- Clip the MCB into a 2 module opening of the plate, fix the plate to the box and switch on.
Electrical work should be done by a licensed electrician. For 240 V AC circuits only — not for solar panel or battery (DC) circuits.
Frequently asked questions
- What is a tiny trip MCB?
- A miniature circuit breaker built like a modular switch. It fits a modular switch plate, protects the point wired through it against overload and short circuit, and resets with its handle after a trip.
- Why double pole instead of single pole?
- It switches phase and neutral together, so the appliance is fully disconnected when switched off or tripped — the usual choice for AC, geyser and pump points.
- Can it replace the DP switch at my AC point?
- Yes, on a modular board with a free 2 module space. Choose the rating for the AC and its cable — typically 16A for a 1 to 1.5 ton AC and 20A to 25A for a 2 ton AC. Unlike a DP switch, it also trips on a fault.
- Does it protect against electric shock?
- No. An MCB trips on overload and short circuit only. Protection against shock from earth leakage needs an RCCB of 30 mA or less in the distribution board.
