The Lovato P1RB1NC20A300 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 P1RB1NC20A300 helps simplify electrical 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 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 supports reliable fault interruption in commercial and industrial electrical installations.
The Lovato P1RB1NC20A300 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. 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.
