The external gateway of the communication circuit breaker connects to the network through WiFi, and synchronizes the power consumption, voltage, current, power and other power information to the mobile phone through the network, so as to realize the wireless control of the circuit breaker opening and closing on the mobile phone, modify the threshold of the protection function, and control whether the various protection functions are turned on. The gateway supports the standard IEEE802.11 b/g/n protocol, has a full TCP/IP protocol stack, and supports WPA/WPA2 security mode.

"Intelligent power distribution" is a fully automated electrical control device, which can completely replace the electrical controller (including leakage protector and air switch) commonly used at present, which not only makes up for the technical deficiencies of existing products, but also has more powerful functions, more intelligent, more safe and reliable, lower cost, and more perfect monitoring of people's electricity. It has realized the leap of intelligent management. It can monitor and protect all the electrical equipment used in the back-end in real time, including overvoltage, lightning strike, leakage, overheating, overcurrent, low voltage, short circuit, overload and other protection measures, so as to protect the electrical equipment you use from damage to the greatest extent, and realize the real-time use of the electrical equipment monitored at the remote computer terminal. This device does not require additional wiring or wiring, and can be simply replaced or installed. Scope of application: It can be widely used in homes, factories, hotels, office buildings, property management, municipal parks, traffic command, street lamp monitoring and other unattended occasions.

The arc fault detection device is a new type of power line protection device, abbreviated as AFDD (Arc fault detection devices). Its main function is to detect and identify dangerous ground arc faults, parallel arc faults and series arc faults, and to drive the device action to disconnect the current in time to avoid electrical fires. It adopts the embedded system digital circuit control and the original arc feature recognition algorithm, which is small in size and strong in function, and integrates the leakage current protection function to realize the automatic monitoring and protection of fault arc and leakage current, and effectively protect the safety of low-voltage distribution lines and electrical equipment and personal safety.

WRB5L Leakage Current Circuit Breaker (RCBO), suitable for AC 50/60Hz rated voltage 230V/400V, rated current 1-63A line, with There are overload protection, short circuit protection, and leakage protection functions, and can also be used for infrequent operation conversion of the line under normal circumstances. It is widely used in industrial, commercial, high-rise and residential places.

WRG5 disconnector is suitable for AC 50/60Hz, rated voltage 230V/400V, rated current 16-125A line, for the connection and disconnection of the circuit under the condition of voltage and no load, for the line and the power supply to be connected or isolated. It is widely used in industrial, commercial, high-rise and residential places.

WRGQ5Z over- and under-voltage automatic reclosing protector is suitable for low-voltage distribution lines for household and similar purposes with an AC rated frequency of 50Hz and a rated voltage of 230/400V (relative neutral voltage of 230V), which can automatically detect the line voltage, automatically disconnect the faulty line when the line overvoltage or undervoltage occurs, and automatically close the line after the line voltage returns to the normal range, so as to ensure the safe operation of the load equipment under the normal voltage.

The FAR6B-U self-resetting over-voltage and under-voltage protector uses a miniature circuit breaker with short-circuit and overload protection as the main switch, and is equipped with an ultra-small intelligent electrical operator with a microprocessor. It can detect the power supply voltage, realize the over-voltage or under-voltage tripping protection, and automatically recloses after the voltage is restored, ensuring the safe operation of the load equipment under normal voltage. It is mainly suitable for occasions where the grid voltage is unstable or for the protection of equipment that is relatively sensitive to voltage fluctuations. It meets the requirements of the Code for Design of Residential Buildings JGJ242-2011 for self-resetting over-voltage and under-voltage protectors. This series of products features a small size, high breaking capacity, reliable operation, stable performance, and a good human-machine interface. The communication function can be added to achieve "remote signaling", "remote measurement", "remote control", and "remote adjustment" (bidirectional communication between the master station and the slave station).
