Why Choose the Lovato P1RB1NC20A030 RCBO?
The Lovato P1RB1NC20A030 is a compact and dependable residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and earth leakage faults. Part of the Lovato Electric P1RB series, it combines overcurrent and residual current protection within a single modular device.
By integrating the functions of a miniature circuit breaker and a residual current device, the P1RB1NC20A030 helps simplify distribution board design, reduce installation time and conserve valuable DIN rail space. Its 1P+N configuration protects the phase conductor while simultaneously switching the neutral conductor.
With a rated current of 20 A, a C tripping characteristic, Type A residual current detection and a rated residual operating current of 30 mA, this RCBO is suitable for final circuits requiring additional protection against electric shock. Its 10 kA short-circuit breaking capacity supports reliable fault interruption in residential, commercial and industrial electrical installations.
Key Advantages
- Combined protection against overloads, short circuits and earth leakage faults.
- 20 A rated current for single-phase final circuits.
