This is a 1-pole+N RCBO, a residual current circuit breaker that protects a circuit against overload, short-circuit and earth leakage faults in one device. It is installed in a distribution board and cuts the power automatically when a fault occurs, offering a space-saving way to protect electrical circuits.
- Combines thermal-magnetic and differential protection in one unit
- Type: 1-pole+N (N2)
- Fits standard distribution board installations
