Lovato P1RB1NC40AC030 1P+N RCBO with 40 A rated current, C tripping curve, 30 mA Type AC residual current protection and 10 kA short-circuit breaking capacity.
Original price was: £92.04.£55.22Current price is: £55.22.
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.
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.

The P1RB1NC40AC030 protects a single-phase electrical circuit against earth leakage, overloads and short circuits by combining RCD and MCB functions within one RCBO.
The Lovato P1RB1NC40AC030 has a rated current of 40 A and uses a C tripping curve.
This RCBO has a rated residual operating current of 30 mA, making it suitable for additional protection against electric shock and earth leakage faults.
Type AC protection detects sinusoidal alternating residual currents and is generally used with conventional AC electrical loads that do not produce pulsating DC leakage.
The device has a rated short-circuit breaking capacity of 10 kA.
The P1RB1NC40AC030 clips onto a standard 35 mm DIN rail and occupies two modules within a suitable distribution board or control panel.
Lovato Electric modular protection devices are used by electrical contractors, panel builders and industrial engineers to provide dependable circuit protection, straightforward installation and compliance with recognised international standards.
