RCCB breakers detect residual current imbalances and disconnect circuits to help reduce electric shock risks. Suitable models and ratings depend on the electrical system.
RCCB (Residual Current Circuit Breaker) is an electrical safety device designed to detect residual current caused by an imbalance between the live and neutral conductors. When a residual current exceeds the device’s specified operating threshold, the RCCB disconnects the circuit to help reduce the risk of electric shock and electrical hazards.
RCCBs are commonly installed in residential, commercial, and industrial distribution boards. They are available in different current ratings, sensitivity levels, pole configurations, and types to suit various electrical system requirements.

Key Features:
When selecting an RCCB, consider the rated current, residual operating current, number of poles, voltage, and RCCB type. An RCCB generally does not provide overload or short-circuit protection on its own, so suitable overcurrent protection, such as an MCB or fuse, must also be provided. Installation should follow applicable electrical standards and manufacturer instructions.
