Why Choose the Lovato P1RE1NB10A300 10 A 1P+N RCBO?
The Lovato P1RE1NB10A300 is a 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to combine residual-current, overload and short-circuit protection in a single modular device. Part of the Lovato P1RE range, it is rated at 10 A with a 10 kA short-circuit breaking capacity.
This model features a type B tripping curve and type A residual-current characteristic, allowing it to detect sinusoidal AC residual currents as well as pulsating DC residual currents. Its rated residual operating current of 300 mA makes it suitable for appropriately designed installations requiring this residual-current threshold.
The P1RE1NB10A300 occupies two DIN modules and mounts on a standard 35 mm DIN rail. The 1P+N configuration switches the phase and neutral conductors, while dedicated indication and operating features help distinguish residual-current operation from overload or short-circuit tripping.
Key Advantages
- Combines MCB and residual-current protection in one compact RCBO.
- 10 A rated current with type B overcurrent tripping characteristic.
- 300 mA rated residual operating current.
- Type A residual-current detection for AC and pulsating DC residual currents.
- High 10 kA IEC short-circuit breaking capacity.
- 1P+N configuration for single-phase circuits with switched neutral.
- Compact two-module DIN-rail format for distribution boards and control panels.
Key Features
- Lovato P1RE series RCBO.
- 1 pole + neutral (1P+N) configuration.
- 10 A rated current (In).
- Type B tripping curve.
- Type A residual-current characteristic.
- 300 mA rated residual current (IΔn).
- 10 kA IEC breaking capacity.
- Two DIN modules wide.
- Contact-status indication.
- Separate operating indication to distinguish residual-current tripping from overload or short-circuit tripping.
- Designed for 35 mm DIN-rail mounting.
Combined Residual-Current and Overcurrent Protection
An RCBO combines the functions normally provided by a miniature circuit breaker and a residual current device. The Lovato P1RE1NB10A300 can disconnect the protected circuit in response to overloads and short circuits while also monitoring for residual current to earth, reducing the number of separate protective devices required within a distribution assembly.
The type B overcurrent curve provides the instantaneous tripping characteristics associated with B-curve circuit protection, while the type A residual-current characteristic responds to both sinusoidal AC and pulsating DC residual currents. Its 300 mA IΔn rating should be selected according to the protection requirements and applicable electrical regulations for the installation.
Typical Applications
- Single-phase electrical distribution boards.
- Industrial control panels.
- Commercial electrical installations.
- Machinery auxiliary circuits.
- Building-services distribution systems.
- Circuits requiring combined overload, short-circuit and residual-current protection.
- Installations specified for a 300 mA type A RCBO.
