## Long description

The Legrand P304 residual current circuit breaker is a high-quality 4-pole electrical protection device engineered to enhance safety in both residential and commercial electrical systems. With a rated current of 40A and a sensitivity of 0.5A, this device is specifically designed to detect AC type leakage currents. By monitoring the balance of current in the circuit, it acts as a critical safety barrier, automatically disconnecting the power supply when a fault is detected to prevent electrical hazards and protect users from indirect contact.
Advantages
This residual current circuit breaker offers robust performance and reliability, ensuring consistent protection for electrical installations. Its 4-pole design allows for versatile integration into three-phase distribution boards, providing comprehensive coverage for complex circuits. The device is built to meet rigorous safety standards, offering peace of mind by effectively mitigating the risks associated with current leakage and potential electrical faults in various environments.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Three-phase electrical circuits
Protection against indirect contact
This device is not suitable for detecting DC component leakage, as it is specifically designed for AC type currents. It should not be used as a primary protection device in circuits where high-frequency interference or specific DC fault currents are expected, as it may not trigger correctly under those conditions.
Key specifications
Number of poles: 4
Rated current: 40A
Sensitivity: 0.5A
Type: AC
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and that the load is properly wired to the output terminals. Once installed, the test button should be pressed to verify the mechanical functionality of the tripping mechanism.
What to consider before purchase
Verify that the 40A rating matches your circuit requirements
Ensure the 0.5A sensitivity is appropriate for your specific safety application
Confirm compatibility with your existing distribution board and DIN rail system
Regularly test the device using the integrated test button at least every six months to ensure the tripping mechanism remains operational and provides reliable protection for your electrical installation.
