## Long description

The Legrand P312 is a high-quality 2-pole residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in modern installations. This device integrates both overload and short-circuit protection with residual current monitoring, ensuring that both the electrical system and users are protected from potential hazards. With a rated current of 40A and a B tripping characteristic, it is designed to handle standard residential and commercial electrical loads effectively.
Advantages
The primary benefit of the Legrand P312 is its dual-function design, which saves space in distribution boards by combining two essential safety features into a single compact unit. Its reliable AC type sensitivity of 30mA ensures rapid detection of leakage currents, significantly reducing the risk of electric shock. The robust construction and high-quality materials used by Legrand guarantee long-term operational stability and durability, making it a dependable choice for maintaining consistent power distribution and safety standards.
Suitable for
Residential electrical distribution boards
Commercial office building circuits
Protection of lighting and general-purpose socket outlets
Small-scale industrial electrical installations
When it may not be suitable
This device is not suitable for circuits requiring DC-sensitive protection, as it is specifically designed for AC type leakage currents. It should not be used in environments where high-frequency interference or specific industrial equipment might cause nuisance tripping without a proper assessment of the electrical load characteristics.
Key specifications
Number of poles: 2P
Rated current: 40A
Tripping characteristic: B curve
Sensitivity: 30mA

Once installed, the device is operated via the front-facing toggle switch. Regular testing using the integrated test button is recommended to ensure the mechanical and electrical integrity of the residual current protection mechanism.
What to consider before purchase
Verify that the 40A rated current matches your circuit requirements
Ensure the B curve characteristic is appropriate for your specific load type
Confirm that the installation environment is compatible with AC type protection
Check the available space in your distribution board for a 2-pole device
Usage recommendations
Perform a manual test of the device using the test button at least every six months to verify that the tripping mechanism functions correctly and provides the intended level of safety.
