Our Residual Current Circuit Breaker line represents dual safety protection devices integrating leakage current protection and overcurrent protection into a single, cohesive unit. They accurately detect residual current in a circuit caused by electric shock or insulation damage, quickly disconnecting the circuit to prevent life-threatening accidents. Simultaneously, they automatically trip in the event of a short circuit or overload, avoiding equipment damage and fire risks, thus building an efficient safety barrier for residential, commercial, and industrial power distribution systems.As a world-class residual current circuit breaker manufacturer, we offer these products with multiple leakage current protection sensitivity levels, including 30mA, 100mA, and 300mA, to adapt to the risk protection needs of different scenarios. They also support multi-pole configurations such as 1P+N and 2P, flexibly meeting the installation requirements of single-phase and three-phase systems. Developed and tested in strict accordance with the IEC/EN 61009 international standard, this series ensures long-term stable operation in harsh environments, providing lasting assurance for electrical safety with reliable quality.
