P1RB1NC06AC300 – RCBO 1P+N CURVE C 6A IDN 300MA TYPE AC
Lovato P1RB1NC06AC300 1P+N RCBO with a 6 A rated current, 300 mA Type AC residual current protection, Type C tripping characteristic and 10 kA short-circuit breaking capacity.
Why Choose the Lovato P1RB1NC06AC300 RCBO?
The Lovato P1RB1NC06AC300 is a compact and dependable residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against earth leakage, sustained overloads and short circuits. Part of the professional Lovato Electric P1RB series, it combines the functions of a residual current device and a miniature circuit breaker within one modular unit.
Featuring a rated current of 6 A, a rated residual operating current of 300 mA and a Type C overcurrent tripping characteristic, the P1RB1NC06AC300 is suitable for low-current circuits supplying equipment with moderate starting currents. Its Type AC residual current characteristic detects sinusoidal alternating residual currents associated with conventional AC electrical loads.
The RCBO has a 1P+N configuration, occupies two DIN modules and provides a short-circuit breaking capacity of 10 kA. Designed for straightforward DIN rail installation, it provides a space-efficient protection solution for industrial control panels, commercial distribution boards, machinery circuits and building services.

Combined Residual Current and Overcurrent Protection
The Lovato P1RB1NC06AC300 combines thermal-magnetic overcurrent protection with residual current monitoring. Its thermal element responds to prolonged overload conditions, while the magnetic mechanism rapidly disconnects the circuit when a high short-circuit current occurs.
The residual current element monitors the balance between the live and neutral conductors. When sinusoidal AC leakage reaches the 300 mA operating threshold, the RCBO disconnects the circuit to help protect wiring, equipment and installations against potentially damaging earth faults.
Typical Applications
- Industrial electrical control panels.
- Machinery control and auxiliary circuits.
- Commercial electrical distribution boards.
- Building services and automation systems.
- Lighting and conventional AC load circuits.
- Manufacturing and processing equipment.
- OEM machinery and electrical assemblies.
- Circuits requiring 300 mA Type AC residual current protection.
