Circuit breakers are widely used switching components in industrial production and daily life, and achieving intelligence is of great significance.The intelligence of circuit breakers has become a new development direction in the field of electrical engineering for power switchgear, power system relay protection, industrial supply and distribution systems, and industrial control network technology.
Strengthening the comprehensive control and management of terminal power distribution by enterprises is an effective means to optimize the use of electricity, ensure personal safety, and prevent electrical fires. The intelligent circuit breaker that integrates protection, measurement, and remote control is the key to achieving control and management of end distribution.
The SFB2A series intelligent miniature circuit breaker is a new type of IoT circuit breaker suitable for AC 230V/400V, 50Hz distribution systems. This product integrates multiple functions such as protection, remote control, energy metering, and safety condition monitoring, which can help users avoid harm and losses caused by safety hazards such as line short circuits, overload, overvoltage and undervoltage, leakage, and overheating of operating equipment. It achieves intelligent power control for application environments such as homes, buildings, apartments, streetlights, and municipal engineering. The product has been put into use in industries such as municipal engineering, commercial real estate, education, and healthcare.

Main technical parameters


Main functions of the intelligent circuit breaker cloud platform
Real time monitoring of status
For the convenience of users to understand the operation status of the end distribution, the platform uses distribution boxes as a navigation method to display the current operation information of each distribution line in a centralized manner. Through the real-time monitoring page, users can understand the energy consumption, event change trends, and statistical information of the distribution box, as well as the opening and closing status, alarm/protection events, energy consumption, current/voltage/power/temperature operation trends, timed opening and closing plans, leakage self inspection, and other information of each circuit breaker.

Remote control of equipment
With the remote opening and closing function of intelligent circuit breakers, the platform can assist users in achieving device start stop control; Combined with a timing strategy, users can also plan the operation schedule of the equipment in advance. Through remote leakage self check, alarm/protection threshold adjustment, leakage self check cycle setting and other functions, users can achieve personalized safety management. The platform ensures the security of remote control operations through password security protection mechanisms.

Scene linkage control

Alarm protection management
The platform has designed a communication method for alarm/protection event information such as switch displacement, overcurrent, overtemperature, overvoltage, overload, short circuit, and leakage of intelligent miniature circuit breakers based on MQTT's message subscription and publishing mode, ensuring fast and reliable transmission of events. The platform pushes events to the corresponding management personnel responsible for the region through event subscription services, and users can obtain real-time information about the events through the APP. The platform simultaneously records the occurrence and end process of events, displaying the frequency of events in the form of trend curves.

Electric energy statistical analysis
A large amount of electricity consumption is mainly transmitted to electrical equipment through end distribution lines such as lighting, sockets, power, and air conditioning. The end distribution lines are usually numerous and scattered in layout, leading to difficulties in managing safety and energy efficiency. The intelligent miniature circuit breaker, which integrates control, energy metering, and safety protection, provides an ideal solution for refined energy management such as energy sub item statistics without changing the basic form of end distribution. The platform has implemented functions such as electricity collection and reading, energy consumption trends, month on month analysis, and visual display.

Trend analysis of operation
When electrical equipment experiences slow aging of phase to phase and ground insulation, electrical parameters such as leakage and voltage will change accordingly. When adding connected electrical equipment or adjusting equipment load, there is a possibility of improper matching of rated power in the distribution system. In response to such hidden dangers, users can analyze the operating trend charts of various electrical parameters to identify key risk nodes in the distribution system and prevent accidents from occurring.

Mobile APP
Users can access real-time data on the opening and closing status, alarm/protection events, energy usage, current/voltage/power, timed opening and closing plans, automatic leakage self inspection, and other information of circuit breakers anytime and anywhere through the APP. The APP can also achieve remote opening and closing control, leakage self check, and quick execution of preset scene linkage control.

By combining the overcurrent, overtemperature, overvoltage and other warning functions of the intelligent circuit breaker, users can quickly learn about the abnormal operating status of the equipment through the APP and take preventive measures in advance. When the intelligent circuit breaker experiences overload, short circuit, or leakage protection causing the opening action, the user immediately receives a message and can quickly locate the fault point and take emergency measures.
Sifei Electric is committed to providing low-cost and high-efficiency solutions for enterprise electricity safety and refined energy management, Intelligent circuit breaker products will gradually be widely used in the next decade. Electricity is the foundation of modern society, and smart cities cannot do without smart electricity usage. In the context of sustainable development and the "dual carbon goal", Sifei Electric looks forward to working together with you for common development!
