Why Choose the Lovato P1RB1NC40A030 RCBO?
The Lovato P1RB1NC40A030 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against earth leakage, overloads and short circuits. Combining residual current and miniature circuit-breaker functions in one device, it provides comprehensive circuit protection while reducing the amount of space required inside a distribution board.
This Lovato Electric RCBO features a 40 A rated current, C tripping curve and 30 mA Type A residual current sensitivity. Type A protection detects sinusoidal alternating residual currents and pulsating DC residual currents, making the unit suitable for modern electrical loads containing electronic components.
With a 1P+N pole configuration, 10 kA short-circuit breaking capacity and compact two-module construction, the P1RB1NC40A030 is suitable for residential, commercial and light-industrial distribution systems. It mounts onto a standard 35 mm DIN rail and complies with IEC/EN 61009-1.
Key Advantages
- Combines earth leakage, overload and short-circuit protection in one device.

Combined Residual Current and Overcurrent Protection
An RCBO combines the functions of a residual current device and a miniature circuit breaker. The Lovato P1RB1NC40A030 disconnects the protected circuit when it detects dangerous earth leakage, sustained overload conditions or high short-circuit currents.
Its Type A residual current characteristic makes it suitable for equipment containing electronic power supplies, rectifiers and control circuits that may produce pulsating DC leakage. The C curve characteristic also provides reliable circuit protection while tolerating the moderate starting currents associated with many commercial and industrial loads.
Typical Applications
- Residential consumer units and distribution boards.
- Commercial lighting and power circuits.
- Industrial control panels and auxiliary circuits.
- Socket outlet and appliance circuits.
- Circuits supplying equipment with electronic power supplies.
- Heating, ventilation and building-services installations.
