Why Choose the Lovato P1RB1NC25A300 RCBO?
The Lovato P1RB1NC25A300 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 miniature circuit breaker and residual current protection functions within a single modular device.
By integrating overcurrent and residual current protection, the P1RB1NC25A300 helps simplify distribution board layouts, reduce installation time and conserve valuable DIN rail space. Its 1P+N configuration protects the phase conductor while simultaneously switching the neutral conductor, making it suitable for single-phase electrical distribution systems.
With a rated current of 25 A, a C tripping characteristic, Type A residual current detection and a rated residual operating current of 300 mA, this RCBO is suitable for equipment, circuit and fire-risk protection applications. Its 10 kA short-circuit breaking capacity provides dependable fault interruption in commercial and industrial electrical installations.

Reliable Combined Circuit Protection
The Lovato P1RB1NC25A300 combines thermal-magnetic overcurrent protection with residual current monitoring. It disconnects the protected circuit when an overload, short circuit or qualifying earth leakage fault is detected, helping protect wiring, connected equipment and the wider electrical installation.
Its Type A residual current characteristic enables detection of sinusoidal alternating and pulsating DC residual currents, making it suitable for many modern electrical loads containing electronic components. The 300 mA sensitivity is generally selected for equipment protection, insulation fault monitoring and reducing risks associated with electrical fires rather than additional personal protection.
Typical Applications
- Commercial electrical distribution boards.
- Industrial power distribution systems.
- Machinery and automation control panels.
- Equipment feeder circuits.
- Lighting and general power circuits.
- Building services electrical installations.
- Circuits requiring combined overcurrent and Type A earth leakage protection.
