P1RB1NC10AC300 – RCBO 1P+N CURVE C 10A IDN 300MA TYPE AC
Lovato P1RB1NC10AC300 residual current circuit breaker with overcurrent protection, featuring a 1P+N configuration, 10 A rated current, C tripping characteristic, Type AC 300 mA residual current protection and 10 kA breaking capacity.
Why Choose the Lovato P1RB1NC10AC300 RCBO?
The Lovato P1RB1NC10AC300 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. As part of the Lovato Electric P1RB series, it combines miniature circuit breaker and residual current protection within a single modular device.
This RCBO features a 1P+N pole configuration, allowing the phase conductor to be switched and protected while the neutral conductor is simultaneously isolated. Its combined design helps simplify distribution board layouts, reduce installation time and conserve valuable DIN rail space compared with installing separate protective devices.
With a rated current of 10 A, a C tripping characteristic, Type AC residual current detection and a rated residual operating current of 300 mA, the P1RB1NC10AC300 is suitable for circuit and equipment protection in commercial and industrial installations. Its 10 kA breaking capacity provides robust performance where higher prospective fault currents may be present.
Key Advantages
- Combined protection against overloads, short circuits and earth leakage faults.
- 10 A rated current for lower-current electrical circuits.
- C tripping characteristic suitable for loads with moderate starting currents.
- Type AC residual current detection for sinusoidal alternating leakage currents.
- 300 mA residual operating current for equipment and fire-risk protection applications.
- 10 kA breaking capacity for reliable fault interruption.
- Compact two-module DIN rail design.

Reliable Combined Circuit Protection
An RCBO combines the functions of an overcurrent circuit breaker and a residual current protective device. The Lovato P1RB1NC10AC300 disconnects the protected circuit when it detects an overload, short circuit or qualifying earth leakage fault, helping prevent damage to wiring and connected equipment.
The 300 mA residual current rating is generally intended for equipment protection, installation monitoring and reducing risks associated with insulation faults. It is not normally selected as a substitute for a 30 mA device where additional personal protection is required.
Typical Applications
- Industrial electrical distribution boards.
- Commercial power distribution systems.
- Machinery and automation control panels.
- Equipment feeder circuits.
- Lighting and general power circuits.
- Circuits requiring combined overcurrent and earth leakage protection.
