P1RB1NC16AC300 – RCBO 1P+N CURVE C 16A IDN 300MA TYPE AC
Lovato P1RB1NC16AC300 residual current circuit breaker with overcurrent protection, featuring a 1P+N configuration, 16 A rated current, C tripping characteristic, Type AC 300 mA residual current protection and 10 kA breaking capacity.
Why Choose the Lovato P1RB1NC16AC300 RCBO?
The Lovato P1RB1NC16AC300 is a compact and reliable 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 P1RB1NC16AC300 helps simplify distribution board design, reduce installation time and conserve valuable DIN rail space. Its 1P+N configuration provides protection for the phase conductor while simultaneously switching the neutral conductor.
With a rated current of 16 A, a C tripping characteristic, Type AC residual current detection and a rated residual operating current of 300 mA, this RCBO is suited to equipment, circuit and fire-risk protection applications. Its 10 kA short-circuit breaking capacity provides dependable fault interruption in commercial and industrial electrical installations.
Key Advantages
- Combined protection against overloads, short circuits and earth leakage faults.
- 16 A rated current for single-phase electrical circuits.
- C tripping characteristic suitable for loads with moderate starting currents.
- Type AC residual current protection for sinusoidal alternating leakage currents.
- 300 mA residual operating current for equipment and fire-risk protection applications.
- 10 kA breaking capacity for reliable short-circuit fault interruption.
- Compact two-module DIN rail design.

Reliable Combined Circuit Protection
The Lovato P1RB1NC16AC300 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 the wider electrical installation.
Its 300 mA residual current sensitivity is generally selected for equipment protection, insulation fault monitoring and reducing risks associated with earth leakage and electrical fires. It is not normally used as a substitute for a 30 mA device where additional personal protection is required.
Typical Applications
- Commercial electrical distribution boards.
- Industrial power distribution systems.
- Machinery and automation control panels.
- Equipment feeder circuits.
- Lighting and general power circuits.
- Circuits requiring combined overcurrent and AC earth leakage protection.
