Smart Circuit Breaker

XUCKY Electric is a large-scale Smart Circuit Breaker manufacturer and supplier in China. We have been specialized in Modular Electrical Terminal Equipment for many years. Our products have a good price advantage and cover most of the South America, Middle East, Africa, Southeast Asia markets. We look forward to becoming your long-term partner in China.

China XUCKY Electric customized the M8LC series residual current operated circuit breaker (hereinafter referred to as circuit breaker) is mainly suitable for distribution networks with frequency of AC 50Hz and rated working voltage of AC 400V. Used in three-phase four-wire power supply and consumption system with neutral point directly grounded, it has functions such as overload, short circuit, phase loss, overvoltage, undervoltage, residual current action protection, etc. It can protect circuit and electrical equipment from damage, and also provide protection for possible grounding fault and indirect personal contact in circuit. The product complies with GB/T14048.2, GB/T14048.4, GB/T32902 and GB/T22387 standard.


What Is a Smart Circuit Breaker?

A smart circuit breaker is an electronic device providing remote and intelligent electrical circuit control. Smart circuit breakers can be operated through a mobile app, web portal, or integrated with other smart home systems, allowing for convenient and efficient electrical system management and monitoring. This article explores a smart circuit breaker's features, construction, and installation. Read our circuit breaker overview article for more details on the working and types of circuit breakers.

Multiple functions

It has protection functions such as residual current, overcurrent, short circuit, etc, as well as practical functions such as automatic reclosing, residual current display, real time load current display, action status indication and trip data display. The product also has functions such as pluggable lightning protection module, four remote functions and special adapter.

The combination of electric operating mechanism and air circuit breaker has been transformed into an integrated type, with reduced installation location and simplified wiring. The operation method with configurable function characteristic can set the required functions such as action current, breaking time and main circuit current according to the actual situation.


Communicability (when this function is required during ordering)

The communication type leakage circuit breaker can record and query detailed data such as the phase sequence that causes the trip, cause and trip time, and has the function of historical data recording; the communication series product adopts RS-485 communication port and have multiple communication protocols to choose from. It can establish communication function with intelligent distribution transformer terminal, upper computer, etc., and achieve remote parameter adjustment, information query and fault parameter download.


Working environment and installation condition

The ambient air temperature shall not exceed +40℃, and the average temperature value within 24 hours shall not exceed +35℃. The lower limit of the ambient air temperature is -20℃; Note: For working condition where the ambient air temperature is above +35℃ or below -20℃, the user should consult with the manufacturer.

The altitude of the installation site shall not exceed 2000m;

The maximum temperature is +40℃, and the relative humidity of the air does not exceed 50%. At lower temperature, there can be higher relative humidity. Special measures should be taken for occasional condensation caused by temperature changes;

In a place without rain or snow erosion;

The pollution level is 3;

The maximum inclination of circuit breaker installation is ±5°;

Installation category: The installation category of the main circuit of the circuit breaker is III, and the installation category of the auxiliary circuit and control circuit is II.

The external magnetic field of the installation site shall not exceed 5 times the geomagnetic field in any direction.
