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.
40 A rated current for higher-load final circuits.
30 mA Type A residual current protection for AC and pulsating DC leakage currents.
10 kA short-circuit rating for dependable fault protection.
C tripping curve suitable for circuits with moderate inrush currents.
Compact two-module DIN rail design helps conserve distribution-board space.

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.
