What Is a Circuit Breaker
The Mekel circuit breaker is a high-performance electrical safety device designed specifically for EV charging stations, providing comprehensive protection for charging infrastructure. Our circuit breaker product line includes residual current circuit breakers (RCCBs, also known as RCBs) and miniature circuit breakers (MCBs), fully compliant with the latest international charging safety standards such as IEC 61851 and IEC 60364-7-722.
Whether used in home AC wallboxes, commercial single-phase or three-phase AC charging stations, or DC fast chargers, Mekel circuit breakers ensure reliable fault protection, leakage current detection, and overload shutdown. Our RCCB portfolio includes Type A + 6mA DC sensitive and Type B RCCBs — covering everything from AC leakage to smooth DC residual current detection. Mekel’s circuit breakers are safe, compliant, and ready for global deployment.
Key Features of Circuit Breaker
High Safety
RCCB will detect any current imbalance between the live and neutral wires. If there is an earth leakage current, it will subsequently trip the circuit and hence protect users from electric shock as well as fire hazards.
Broad Charging Scene Aid
We give RCCB gear for all kinds of spots and gear, if it is home or business, one-phase or three-phase AC charge, or even DC charge, we can suit your wants.
Global Approval and Quality Promise
Our RCCB items only come from best makers, meet the most strict EU/US paper requirements, and have been sent to Europe, America, the Middle East and Southeast Asia.
Great Client Help
We give no-charge product advice to assist you in making the right pick for your business. We also give no-charge tech help during product setup to assist you avoid issues as soon as possible and lower buyer gripes.
