High-Sensitivity RCBO with Fast Response and Reliable Overcurrent Protection

RCBO offers several features including integrated protection that combines overcurrent and leakage protection functions into a single device. Depending on the application, it offers different sensitivity levels such as 10mA, 30mA, 100mA and 300mA and matches the load requirements of the circuit with current levels of 16A, 20A or 32A. It offers various pole configurations such as single pole (SP) or double pole (DP) to suit different electrical systems. The device continuously monitors the current in the hot and neutral wires and trips if there is an imbalance (indicating leakage to ground) or if the current exceeds the rated capacity due to overload or short circuit.

RCBOs are widely used in domestic installations, especially in wet areas such as kitchens and bathrooms, to protect domestic circuits. They are also essential in commercial and industrial settings, where they protect equipment and personnel in environments with high electrical loads. They are also used in critical circuits that require overcurrent and leakage protection, such as sensitive equipment or high-risk areas. Their versatility makes them a key component in modern electrical systems.

RCBOs are designed to save space as they combine two functions into one device, reducing the need for separate RCDs and MCBs. They also improve safety by providing comprehensive protection against electrical hazards, including leakage and overcurrent faults. They ensure selective tripping, which means that only the faulty circuit is disconnected, minimizing interference with other parts of the electrical system. This makes them an efficient and reliable solution for both residential and industrial applications.

Installation and maintenance of RCBOs must be carried out by a qualified electrician in accordance with local electrical regulations (e.g. IEC 61009 or BS EN 61009). Regular testing using the test button on the device is recommended to ensure proper functionality and continued safety. RCBOs play a vital role in modern electrical installations by combining overcurrent and residual current protection in one device, providing dual protection and enhancing the overall safety of the electrical system.
