## Summary description

Legrand residual current circuit breaker (RCCB) P304, 4-pole, rated 25 A with 30 mA sensitivity, type AC. Designed to detect and disconnect earth leakage currents in three-phase installations, providing protection against electric shock and fire risk from insulation faults. Suitable for industrial and commercial electrical distribution panels requiring AC-type residual current protection.

## Long description

Legrand Residual Current Circuit Breaker P304 is a 4-pole device rated at 25 A with 30 mA sensitivity, type AC. It monitors imbalance between phase and neutral currents in three-phase installations and trips when earth leakage currents exceed the set threshold. The unit is intended for use in industrial and commercial electrical distribution panels where AC-type residual current protection is required to reduce the risk of electric shock and to limit fire hazards caused by insulation faults.
Advantages
The RCCB provides fast disconnection of faulty circuits when leakage currents reach 30 mA sensitivity, offering personnel protection and reducing the chance of fire due to insulation failure. Its 4-pole construction allows use in three-phase systems with neutral, enabling simultaneous protection of all conductors. The AC type detects sinusoidal alternating residual currents and is compatible with standard alternating-current loads and installations. Compact design facilitates mounting in distribution boards alongside other protective devices.
Suitable for
 Three-phase commercial and industrial distribution panels with neutral conductor
 Circuit protection where personnel shock protection is required (30 mA threshold)
 Sites requiring AC-type residual current detection for standard AC loads
Key specifications
 Poles: 4-pole configuration for three-phase systems with neutral
 Rated current: 25 A
 Residual operating current: 30 mA
 Type: AC (sensitive to sinusoidal alternating residual currents)
 Function: Earth leakage detection and automatic circuit disconnection
How to use
Install the device on a compatible DIN rail inside the distribution board according to local electrical codes and the installation instructions provided by the system designer. Connect the three phase conductors and neutral to the corresponding terminals and ensure the supply is isolated before wiring. After installation, restore supply and test the RCCB using a test button if available or a qualified test procedure to verify correct tripping at leakage conditions. Periodic functional testing and visual inspection are recommended to confirm continued operation.
Usage recommendations
Ensure selection matches site requirements: use this AC-type RCCB where residual currents are expected to be sinusoidal and where 30 mA sensitivity is appropriate for personnel protection. For installations with pulsating DC components or electronic loads, consider devices with broader detection characteristics. Follow local regulations for testing intervals and maintenance.
