Residual Current Circuit Breakers (RCCB)
A residual current relay is a protection device that measures the difference between the current going to and returning from the circuit and opens the circuit when the current leaking to earth reaches the tripping threshold; it is also called a residual current device or RCCB. It is used in residential, commercial and industrial panels to protect people against electric shock and to reduce the fire risk arising from insulation faults. The category includes the ABB F202 and F204, Schneider Electric Acti9 iID, Siemens 5SV and Chint NL1 series; 2- and 4-pole products in rated currents such as 25 A, 40 A and 63 A, with 30 mA and 300 mA thresholds, and of AC and A type are listed. Choose the number of poles according to the number of phases of the installation, the rated current according to the line load and the fuse it will work with, the residual current threshold according to the purpose of the protection (30 mA for personal protection, 300 mA for fire protection), and the type according to the connected devices. Type A detects pulsating DC components in addition to sinusoidal residual currents. Except for combined types with overcurrent protection, a residual current relay does not provide protection against overload and short circuit; it does not replace a miniature circuit breaker.

How to choose Residual Current Circuit Breakers (RCCB)
A residual current relay is a protection device that measures the difference between the current going to and returning from the circuit and opens the circuit when the current leaking to earth reaches the tripping threshold; it is also called a residual current device or RCCB. It is used in residential, commercial and industrial panels to protect people against electric shock and to reduce the fire risk arising from insulation faults.
- Separate overcurrent/leakage protection, motor starting and local isolation requirements.
- Select rated current, pole count and breaking capacity (kA) from the installation calculation.
- Match coil voltage, auxiliary contacts and tripping curve to the control circuit and load type.
