Why Choose the Lovato P1RB1NC40A300 RCBO?
The Lovato P1RB1NC40A300 is a high-performance residual current circuit breaker with overcurrent protection (RCBO) engineered to provide dependable protection against earth leakage, overloads and short circuits. Combining the functions of an RCD and miniature circuit breaker into a single compact device, it delivers comprehensive circuit protection while saving valuable space within electrical distribution boards.
Featuring a 40 A rated current, C tripping curve and 300 mA Type A residual current protection, this RCBO is well suited to applications where equipment protection and fire prevention are required rather than additional personal protection. Type A technology detects both alternating residual currents and pulsating DC residual currents generated by modern electronic equipment.
With its 1P+N configuration, 10 kA breaking capacity and compact two-module design, the P1RB1NC40A300 is ideal for commercial, industrial and building service installations. Manufactured to IEC/EN 61009-1, it provides reliable long-term protection in demanding electrical environments.
