Why Choose the Lovato P1RE1NB40A030 RCBO?
The Lovato P1RE1NB40A030 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined overload, short-circuit and residual-current protection in low-voltage electrical installations. Part of the Lovato P1RE series, it combines the functions of an MCB and residual-current protective device in a single modular unit.
The P1RE1NB40A030 has a rated current of 40 A, a B tripping characteristic and a rated residual operating current of 30 mA. This combination makes it suitable for single-phase final circuits requiring both overcurrent protection and sensitive residual-current detection.
With a specified short-circuit breaking capacity of 10 kA, the P1RE1NB40A030 provides robust fault protection for distribution boards and electrical panels. Its 1P+N configuration is designed for single-phase circuits with phase and neutral switching, while the modular DIN-rail format simplifies integration into modern electrical distribution systems.
Key Advantages
- Combines residual-current, overload and short-circuit protection in one device.
- 40 A rated current for higher-current single-phase circuits.
- B tripping characteristic for circuits with relatively low inrush currents.
- 30 mA residual operating current for sensitive earth-leakage protection.
- 10 kA short-circuit breaking capacity for dependable fault interruption.
- 1P+N configuration for phase and neutral switching.
- Compact modular construction helps reduce distribution-board space requirements.

Reliable & Durable Combined Circuit Protection
An RCBO combines residual-current detection with thermal and magnetic overcurrent protection, allowing a single device to protect a circuit against earth leakage, overload and short-circuit faults. The Lovato P1RE1NB40A030 provides these functions in a compact modular format suitable for single-phase electrical distribution.
Individual RCBO protection also enables circuits to be protected independently, helping limit the effect of a fault to the affected circuit. With its 40 A rating, 30 mA sensitivity and 10 kA breaking capacity, the P1RE1NB40A030 is well suited to demanding commercial, industrial and building installations.
Typical Applications
- Single-phase final circuits requiring combined protection.
- Commercial and industrial distribution boards.
- Building electrical installations.
- Industrial control and auxiliary power circuits.
- Electrical equipment and machinery supplies.
- Distribution panels requiring 30 mA residual-current protection.
