RS Breakers & Controls stocks residual current circuit breakers (RCCBs) and residual current devices (RCDs) from leading global manufacturers. These specialized circuit breakers detect leakage current and provide essential ground fault protection. Our technical team is available 24/7. All previously used units are tested to ANSI and CSA standards with a detailed test report and full 2-year warranty.
Residual current circuit breakers (RCCBs) are protective devices that detect leakage current flowing to earth and automatically disconnect the circuit. Unlike GFCI circuit breakers designed primarily for personnel protection, RCCBs are available in sensitivity ratings from 10mA to 300mA or higher. These circuit breakers provide ground fault protection only — for combined protection, residual current circuit breakers with overcurrent protection (RCBOs) integrate both functions.
Residual current circuit breakers are essential safety devices in commercial and industrial electrical systems. RS Breakers & Controls provides these circuit breakers in a variety of sensitivity ratings and pole configurations.
Our technical team can assist with proper selection of circuit breakers based on your system’s earthing arrangement and applicable code requirements.
