1 & 2 way metal MCB box (ECO) — a surface enclosure for one or two MCB modules on a dedicated circuit such as an AC, geyser or water pump.
- Holds one or two MCB modules — for example one double pole (DP) MCB or DP isolator.
- Sheet-steel body with a white powder-coated finish.
- Screw-fixed front cover with a window for the MCB handles.
- ON/OFF marking and label spaces for one or two circuits on the cover.
- 35 mm DIN rail inside for snap-on MCBs, isolators and RCCBs.
- For indoor surface mounting; sold empty, so you fit the MCB, isolator or RCCB you need.
- Suits AC, geyser, water pump and kitchen-appliance circuits.
An MCB box (MCB enclosure) houses miniature circuit breakers on the wall, right where a circuit needs its own protection or switch. "Way" means one module — the width of one single pole MCB — so a 1 & 2 way box holds one or two modules.
The ECO build gives you a steel body with a neat printed cover at an economical price.
What fits in a 1 & 2 way box
- One double pole (DP) MCB or DP isolator.
- One 2-pole RCCB.
- Two single pole (SP) MCBs.
Where to use it
- Dedicated circuit for a split AC (indoor or outdoor unit).
- Geyser, water heater or water pump circuit.
- Kitchen appliances — oven, induction cooktop, dishwasher.
- Sub-circuits in shops and offices, gate motors, CCTV and UPS points.
How to install
- Switch off the supply and fix the box on a flat indoor wall with screws.
- Bring the cable in, snap the MCB onto the DIN rail and connect it.
- Keep the earth wire continuous through to the load.
- Fill any unused way with a blanking plate, then fit the cover so only the MCB handles are exposed.
Electrical work should be done by a licensed electrician with the supply switched off.
Frequently asked questions
- What does "1 & 2 way" mean on an MCB box?
- It is the number of single pole MCB modules the box holds. A 1 & 2 way box takes, for example, one double pole (DP) MCB or DP isolator, or two single pole (SP) MCBs.
- PVC or metal MCB box — which should I buy?
- PVC is light, rust-free and economical for dry indoor spots. Metal (ECO or HEAVY) is tougher against knocks and can be earthed — better for shops, workshops and commercial sites. HEAVY is the sturdiest option.
- Is the MCB included?
- No. The enclosure is sold empty. Add the MCB, isolator or RCCB you need — see our SP and DP MCBs and DP isolators.
- Is an MCB box the same as a distribution board (DB)?
- No. A DB has busbars that feed several outgoing circuits from one incomer. An MCB box simply houses a few devices on a DIN rail for a single circuit or appliance.
- Can it be used outdoors?
- No. It is an indoor enclosure. For rain-exposed or wet areas, use a weatherproof (IP-rated) enclosure.
