Smart WiFi Circuit Breaker – Construction, Installation and Working

Smart WiFi Circuit Breaker – Automatic Remote Control Protection

In the era of 3G, 4G, and 5G, smartphones are equipped with music players, cameras, email, internet connections, and the ability to make calls to friends and relatives.

But why discuss phone calls when we’re supposed to be talking about circuit breakers and protection? Well, if smartphones can handle all these important tasks, why can’t we use them to control our circuit breakers? Electricians and sparkies are just as tech-savvy as anyone else. So, we should welcome smart home automation as well.

Smart WiFi Circuit Breaker - Automatic Remote Control Protection

So you got the idea that we are talking about smart WiFi remote control circuit breakers. Yes, they exist. The smart WiFi circuit breaker can control the ON / OFF position through ISC when connected to the WiFi and an active internet connection router.

We will be talking about the Single Pole (1P), two poles (2P), three poles (3P) and four poles (4P) Smart WiFi Circuit breakers with rating and specifications.

Obliviously, this smart circuit breaker can be used to transform the ordinary household wiring into a smart system with automation. For example, with the scheduled operation, you can turn OFF and ON a fan, heater, washing machine, water pump motor, etc at a specific time and they can be switched ON/OFF automatically in schedule time operation. The time setting can be done through a smartphone instead of manual operation.

Construction of WiFi Circuit Breaker

WiFi circuit breakers are same like normal and ordinary CBs expect there is an antenna for WiFi signals and a special mechanical switch mechanism for automatic ON/OFF operation as shown in the following fig.Construction of a Smart WiFi Circuit Breaker

The following figure shows the nameplate rating data of Smart WiFi MCB.

How to Wire and Install a Smart WiFi Circuit Breaker?

It is the same like an ordinary circuit breaker (which can be seen in our home distribution board) expect there is an antenna for remote control through WiFi in the smart circuit breaker.

The upper portion is input (Line and Neutral) while the lower is output. In some cases, The incoming lines are connected to the lower portion in our home distribution broads, in that case, you may upside down the smart circuit breaker and install in the existing distribution board for proper operation.

After installation, simply install the iOS or Android app by scanning the QR code on the product box. After installing the app, you may pair the device and can set the automatic operation or scheduled time operation through the smartphone.WiFi Circuit Breaker Remote Control through Smartphone

Note: If you are not sure how to install an MCB to the existing distribution board, contact a licensed electrician as playing with electricity is dangerous which leads to serious damage and injuries. For more details, refer to the user manual for step by step installation instruction.

Applications of Smart WiFi Circuit Breakers

Smart WiFi Circuit breakers can be used to control and protect various types of electrical appliances far away from the installed device location remotely through smartphone such as water pump motors, electric heaters, electric water geyser, air conditioner / refrigerator, washing machine, TV, fan, bulb etc. It provides surge, short circuit, overload and overvoltage protection.Smart Home Automation through WiFi Circuit Breaker

It’s your turn now. Lets us know in the comment box below what are your views / experience with smart WiFi circuit breaker. Will you go for it in the future or will stick to the ordinary CBs.

  1. What make are they? The 18th edition regs say that you can only fit breakers that match the manufacturer of the board. All boards are slightly different and gone are the days we use to mix and match. Don’t get me wrong it’s a fantastic idea and glad they are finally here but need to make sure we still conform to current regs!!!

    1. It’s good in these modern technology.
      But there is a control switch in between circuit breaker & Appliance,so how could be operate it, it’s more good if same technology could be use between appliance and switch.

  2. Can this, or another product, be used for the mains breaker (breaker for incoming mains as opposed to individual house ciruits)? I have a need to be able to remotely control (wifi or ethernet is fine) the main breaker in the house.

  3. I’m impressed with the skills I have received from this field. I’m looking forward to do more projects with you.

  4. Hi,
    I can’t find any information how to reset this breaker to factory default settings. I would like change the WiFi router as the old one has to short range and device loosing connection.

  5. Not impressed being a ret master electrician 20 years in the field, A breaker is designed to trip when encountering a overload . short, etc and to find the problem first , and than manually re setting the breaker with your finger, This thing will wind up burning alot of house’s and buildings down . I would never use one ret or not just asking for trouble !
