Why Choose the Lovato P1RB1NC20AC030 RCBO?
The Lovato P1RB1NC20AC030 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 residual current device, the P1RB1NC20AC030 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 AC 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.
- C tripping characteristic suitable for loads with moderate starting currents.
- Type AC residual current protection for sinusoidal alternating leakage currents.
- 30 mA residual current sensitivity for additional personal protection.
- 10 kA breaking capacity for dependable short-circuit fault interruption.
- Compact two-module DIN rail design.

Reliable Combined Circuit Protection
The Lovato P1RB1NC20AC030 combines thermal-magnetic overcurrent protection with residual current monitoring. It disconnects the protected circuit when an overload, short circuit or qualifying AC earth leakage fault is detected, helping protect wiring, connected equipment and people.
Its 30 mA residual current sensitivity makes it suitable for appropriately designed final circuits requiring additional protection against electric shock. Type AC protection is intended for circuits where sinusoidal alternating residual currents are expected and should be selected according to the connected equipment and installation requirements.
Typical Applications
- Residential consumer units.
- Commercial electrical distribution boards.
- Industrial control panels.
- Lighting circuits.
- Socket outlet circuits.
- General-purpose single-phase final circuits.
- Equipment feeder circuits.
