What is a residual current circuit breaker (RCCB)?
A residual current circuit breaker disconnects a circuit when current leaks to earth, protecting people from electric shock and reducing fire risk. An RCCB detects leakage only; an RCBO combines leakage protection with overload and short-circuit protection in one device.
What buyers compare
- Rated residual current (for example 30 mA or 100 mA)
- Type AC, A, F or B leakage detection
- Rated current and number of poles
- RCCB only, or RCBO with overcurrent protection
- Standard: IEC 61008 (RCCB) or IEC 61009 (RCBO)
