RCBOs

Benefits at a glance:

  • Combine the functions of a residual current device (RCD) and a miniature circuit breaker (MCB) in a single device. This integration allows for both overcurrent protection and protection against earth leakage faults.
  • RCBOs provide enhanced safety by quickly disconnecting the circuit in the event of a fault, such as a short circuit, overload, or leakage to earth. This rapid response helps prevent electric shock and fire hazards.
  • Each RCBO typically protects a single circuit, providing individual protection for specific areas or devices. This granularity allows for better identification of faults and easier troubleshooting.
  • RCBOs can be selected and coordinated to work together in a system, ensuring that only the circuit affected by the fault is disconnected while leaving the rest of the installation operational. This selective coordination helps minimize downtime and disruption.
  • The combination of overcurrent protection and residual current protection makes it easier to identify the type of fault that triggered the disconnection. This facilitates troubleshooting and maintenance.

An RCBO (Residual Current Breaker with Overcurrent) protects against two kinds of fault by combining the functionalities of both MCBs and RCDs. In short, they protect circuits by tripping if they detect abnormal conditions or overcurrent, while also tripping to protect human lives in the event of earth leakage caused by contact with an exposed live wire.
