1 module 4 step fan regulator for ceiling fans, 240V AC — a rotary knob with four marked speeds, made to clip into a modular switchboard.
- Four fan speeds, marked 1 to 4 around the knob.
- Step-type control: each position gives a fixed, repeatable speed.
- Only 1 module wide — fan control that fits on a crowded plate.
- Rated for a 240 V AC single-phase supply.
- Made for ceiling fans — not for dimming lights.
- Two flying leads: it is wired in series with the fan, as shown on the back label.
- Vented body lets heat escape; marked Made in India.
A step fan regulator sets the speed of a ceiling fan in fixed steps. This mini regulator gives four speeds and takes just one module on a modular switchboard — useful where the plate is already full of switches and sockets.
Step regulators like this typically use capacitors rather than a resistance coil, so they run cooler and waste far less power at low speeds than old resistance-type regulators.
Want finer control or a bigger knob? The 2 module medium regulator has five steps. For lights, use a dimmer instead — a fan regulator will not dim lamps properly.
Where to use it
- Bedrooms, halls and living rooms with a ceiling fan.
- Switchboards with only one module free.
- Offices, shops and classrooms where each fan needs its own control.
- Replacing a worn-out regulator on a modular board.
How to install
- Switch off the supply at the MCB.
- Connect the two leads in series in the phase wire between the fan switch and the fan; the neutral goes straight to the fan.
- Clip the regulator into the plate frame and fit the plate.
- Switch on and try every step from 1 to 4.
Electrical work should be done by a licensed electrician with the supply switched off. Use one regulator per fan, and never use it for lights.
Frequently asked questions
- 4 step or 5 step regulator — what is the difference?
- A 4 step regulator gives four fixed fan speeds; a 5 step gives five, so each change in speed is a little smaller. Both are for ceiling fans.
- Can I use a fan regulator to dim lights?
- No. A step regulator is built for fan motors and will not dim lamps properly. Use a light dimmer — see our 450W mini and medium dimmers.
- Will it work with a BLDC fan?
- Most BLDC (energy-saving) fans are controlled by their own remote and should be wired through a plain switch, not a regulator. Follow the fan maker's instructions.
- Does a step regulator save electricity?
- Compared with old resistance regulators, yes. Step regulators typically use capacitors, so at low speed the fan draws less power and very little is wasted as heat.
- Can one regulator run two fans?
- It is made to control one ceiling fan. Wire each fan through its own regulator.
- Where does it fit?
- In one module of a modular plate on a concealed or surface box. Clip designs differ between switch ranges, so check one module first if you are mixing makes.
