Why Choose the Lovato P1RB1NC40AC030 RCBO?
The Lovato P1RB1NC40AC030 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against earth leakage, overloads and short circuits. By combining residual current and miniature circuit-breaker functions within one device, it provides comprehensive protection while conserving valuable space inside distribution boards and control panels.
This Lovato Electric RCBO features a 40 A rated current, C tripping curve and 30 mA Type AC residual current sensitivity. Type AC protection detects sinusoidal alternating residual currents and is suitable for conventional electrical circuits containing predominantly resistive or inductive AC loads.
With a 1P+N pole configuration, 10 kA short-circuit breaking capacity and compact two-module construction, the P1RB1NC40AC030 is suitable for residential, commercial and light-industrial electrical distribution systems. The device mounts onto a standard 35 mm DIN rail and conforms to IEC/EN 61009-1.
Key Advantages
- Combines earth leakage, overload and short-circuit protection within one device.

Combined Residual Current and Overcurrent Protection
The Lovato P1RB1NC40AC030 combines the functions of a residual current device and a miniature circuit breaker. It disconnects the protected circuit when it detects dangerous earth leakage, sustained overload conditions or high short-circuit currents, helping protect people, wiring and connected equipment.
Its 30 mA Type AC residual current sensitivity is intended for circuits where sinusoidal AC leakage currents may occur. The C curve characteristic provides reliable protection while accommodating moderate inrush currents from lighting, transformers and other conventional electrical loads.
Typical Applications
- Residential consumer units and distribution boards.
- Commercial lighting and power circuits.
- Socket outlet circuits.
- Heating and ventilation installations.
- Building-services distribution systems.
- Industrial control-panel auxiliary circuits.
