The ZMEM1L series residual current protective circuit breaker (with automatic reclosing function) is a comprehensive intelligent residual current operated circuit breaker that integrates a residual current protection relay, a leakage circuit breaker, and an electronic molded case circuit breaker, while also incorporating overload protection, short-circuit protection, overvoltage protection, undervoltage protection, phase loss protection, neutral break protection, surge protection, automatic reclosing, remote switching functions, and communication capabilities. It is suitable for low-voltage power grids on the low-voltage side of distribution transformers where the system adopts a three-phase four-wire configuration with a directly grounded neutral point (TT configuration), providing indirect contact protection against electric shock hazards; it can also protect against grounding faults in lines or electrical equipment, as well as overcurrents, short circuits, undervoltage, overvoltage, phase loss, and the breaking of the neutral line on the power supply side.

The residual current operated circuit breakers produced by our company are characterized by reliable performance, ease of installation and operation, and a comprehensive range of specifications. They are suitable for users across various regions and meet diverse environmental requirements, aligning with all intelligent grid management standards. Additionally, they offer multiple models and configurations—including left-zero, right-zero, LCD display, and digital display options—making them well-suited to the requirements of State Grid Corporation in different provinces and regions. Our company is one of the leading manufacturers in China offering the most comprehensive array of reclosing specifications.
