In the era of smart homes and intelligent electrical systems, one technology that’s been making waves is the smart circuit breaker. At Mr. Dee’s Electric Service, we believe in bringing you the latest innovations to enhance your electrical system’s efficiency and safety. In this comprehensive guide, we will delve into the world of smart circuit breakers, exploring their definition, features, functionality, installation process, and their various applications.


Smart circuit breakers represent a revolution in the realm of electrical circuit control. Unlike their traditional counterparts, these electronic devices offer remote and intelligent control over your electrical circuits. They are designed to be operated through various means such as a mobile app, web portal, or integration with other smart home systems. This level of control allows for the convenient and efficient management and monitoring of your electrical system, setting it apart from standard circuit breakers.


Smart circuit breakers offer a host of features that significantly enhance the management of your electrical systems:

Efficient Communication

Unlike traditional circuit breakers, which rely on simple mechanical switches, smart circuit breakers utilize advanced sensors like current and temperature sensors. These sensors monitor electrical currents in real time, detecting irregularities or faults promptly. For instance, if a circuit is supposed to draw 10A but due to a fault, it’s drawing 20A, a smart circuit breaker will detect this and immediately cut off power to prevent damage or danger. This crucial information can also be communicated to a central system, such as a smart home hub, which can alert you to the problem. Thanks to advanced algorithms and machine learning, smart circuit breakers can even predict electrical failures before they occur, enabling preventive maintenance and reducing downtime.

Monitoring Energy Usage

Smart circuit breakers are capable of measuring electrical data with high precision. This includes tracking electricity usage, voltage, current, power, and frequency. Visualizing this data makes it easy to implement case-specific electricity metering and conduct quality checks on the power grid. The platform can manage and store electricity data, allowing you to view detailed electricity usage data for both recent weeks and years, right on your mobile app.

Remote Control and Protection

One of the most convenient aspects of smart circuit breakers is the ability to control them remotely. Whether you’re away from home or simply want to manage your devices from the comfort of your couch, a mobile app allows you to open or close the circuit breaker with ease. This remote control is invaluable for outdoor devices or when you’re not on-site. Furthermore, smart circuit breakers can be programmed to take specific actions when issues occur, providing added safety and convenience.

Choice of Energizing Circuits

Traditional circuit breakers require physical flipping of breakers to activate or deactivate circuits. Smart electrical panels provide a more convenient solution. Users can manually control circuits and establish schedules based on priority. Critical loads like refrigeration and heating can remain active at all times, while non-critical circuits can be turned off entirely. This flexibility is a game-changer when it comes to customizing your electrical system.


Smart circuit breakers support alarm systems, ensuring you’re promptly notified of any issues. These notifications can be customized to take specific actions when certain problems arise, adding an extra layer of protection and control to your electrical system.

How Does a Smart Circuit Breaker Work?

The functionality of a smart circuit breaker can be divided into electromagnetic and electronic components:

Electromagnetic Component

The electromagnetic component in a smart circuit breaker panel operates much like a traditional circuit breaker. It provides overload protection, tripping the circuit in the event of an overcurrent or a short circuit fault.

Electronic Part

The electronic component of the smart breaker consists of one or more circuit boards integrated with control and communication modules. These circuit boards receive instructions and information through signals from remote control terminals, such as mobile apps or computer programs. They collect and record necessary data and transmit it back to the remote terminal, allowing real-time remote control and seamless management.


Installing a smart circuit breaker is similar to installing a regular one, with the addition of a Wi-Fi-enabled antenna for remote control. The process involves identifying the input and output sides of the circuit breaker, connecting the power supply lines, and pairing your smartphone with the circuit breaker using a mobile app.

For detailed step-by-step instructions, refer to the user manual provided by the manufacturer.

Selecting a Smart Circuit Breaker

When choosing a smart circuit breaker, consider the following factors:

  • Working Voltage: Determine whether you need a single-phase or three-phase circuit breaker based on your requirements.
  • Current Rating: Select a circuit breaker rated for the maximum current your system will handle.
  • Breaking Power: Ensure the circuit breaker can interrupt the current flow without damage to your equipment.
  • Closing Power: Consider the maximum current the device can withstand without damage during normal operation.
  • Number of Poles: Choose the appropriate number of poles for your electrical system.
  • Communication Protocol: If you plan to integrate the circuit breaker into a larger control system or monitoring application, consider the communication protocol.


Smart circuit breakers find applications in various settings:

Residential and Commercial Buildings

In residential and commercial buildings, smart circuit breakers provide real-time data on energy usage. They allow you to monitor and control energy consumption at the circuit level, offering insights into power consumption and enhancing electrical system safety and reliability.

Industrial Settings

In industrial settings, smart circuit breakers monitor and control power usage at the circuit level, improving energy management and equipment maintenance. They also offer safety features like fault detection and rapid shut-off.

Data Centers

Data centers benefit from smart circuit breakers by gaining insights into power usage, optimizing energy consumption, and enhancing the safety and reliability of electrical systems.

Renewable Energy Systems

Smart circuit breakers play a crucial role in renewable energy systems. They help monitor and control the flow of electricity, ensuring efficient and safe operation, especially in systems with multiple sources like solar panels and wind turbines.


Q: What kind of devices can I connect to a smart circuit breaker? A: Generally, any electrical device connected to a traditional circuit breaker can be connected to a smart circuit breaker. This includes lights, ceiling fans, air conditioners, heaters, refrigerators, and washing machines.

Q: Can I control a smart circuit breaker remotely using a smartphone or other device? A: Yes, you can control a smart circuit breaker remotely using a smartphone or other devices via Wi-Fi or other connection protocols.
