Residual Current Operated Circuit Breaker (RCBO)

Residual Current Circuit Breakers with Overcurrent Protection (RCBOs)

RCBOs integrate dual protection functions into a single device, combining the capabilities of Residual Current Circuit Breakers (RCCBs) and Miniature Circuit Breakers (MCBs). They provide comprehensive protection against both leakage currents to ground and overcurrents such as overload and short circuit conditions.

Dual Protection: Offers leakage current protection typical of RCCBs, preventing electric shocks from ground faults, and overcurrent protection typical of MCBs, safeguarding against overloads and short circuits.
Application Versatility: Ideal for protecting both individuals and connected equipment in residential, commercial, and industrial environments.
Enhanced Safety: Ensures safety by disconnecting the circuit in the event of leakage or overcurrent, protecting against electrical hazards and equipment damage.
Compliance: Meets international standards for electrical safety and performance, ensuring reliability and peace of mind.
