Why Choose the Lovato P1RE1NB32A300 32 A 1P+N RCBO?
The Lovato P1RE1NB32A300 is a 1P+N residual current circuit breaker with overcurrent protection (RCBO) that combines residual-current, overload and short-circuit protection in a single modular device. Part of the Lovato P1RE range, it has a rated current of 32 A and an IEC short-circuit rating of 10 kA.
This model combines a B tripping curve with a type A residual-current characteristic and a rated residual operating current of 300 mA. The type A characteristic provides detection of sinusoidal AC and pulsating DC residual currents, making the device suitable for appropriately specified single-phase electrical circuits.
Rated for 230 V AC at 50/60 Hz, the P1RE1NB32A300 occupies two DIN modules and mounts on a standard 35 mm DIN rail. Its combined protective functions and compact modular construction make it suitable for industrial, commercial and building electrical distribution systems requiring a 300 mA residual-current threshold.

Combined Residual-Current and Overcurrent Protection
An RCBO combines the functions of a miniature circuit breaker and a residual-current protective device within one unit. The P1RE1NB32A300 therefore provides protection against overloads and short circuits while simultaneously monitoring residual current to earth, allowing several important circuit-protection functions to be incorporated into a single two-module device.
The type A residual-current characteristic detects sinusoidal AC and pulsating DC residual currents, while the B curve defines the device's overcurrent tripping behaviour. With its 300 mA residual-current rating, 32 A nominal current and 10 kA short-circuit rating, the P1RE1NB32A300 should be selected according to the protection requirements and applicable electrical regulations of the installation.
Typical Applications
- Single-phase electrical distribution boards.
- Industrial control panels.
- Commercial electrical installations.
- Building-services distribution systems.
- Machinery and equipment circuits.
