## Summary description

The Legrand DX3 P304 residual current circuit breaker is a 4-pole protective device designed for electrical safety. It features a 100A rated current and 30mA sensitivity, classified as Type A for detecting AC and pulsating DC residual currents. This device is essential for preventing electric shocks and protecting circuits in residential, commercial, and industrial electrical installations.

## Long description

The Legrand DX3 P304 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide reliable electrical protection in various environments. Designed to monitor electrical circuits, this device automatically disconnects power when it detects a residual current, thereby preventing hazardous electric shocks and mitigating the risk of fire caused by insulation faults. With a robust construction and advanced sensing technology, it serves as a critical component for maintaining safety in modern electrical distribution systems.
Advantages
This circuit breaker offers superior reliability through its Type A classification, which allows it to detect both standard alternating current (AC) and pulsating direct current (DC) residual currents. Its 4-pole configuration makes it highly versatile for three-phase electrical systems, ensuring comprehensive protection across all phases and the neutral wire. The device is built to withstand demanding operational conditions, providing long-term durability and consistent performance in residential, commercial, and industrial settings.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Industrial machinery and equipment circuits
Protection of sensitive electronic devices
General electrical safety upgrades
This device may not be suitable for applications requiring a higher sensitivity than 30mA, such as specialized medical equipment or specific high-precision laboratory environments. It is also not intended for use in circuits where the load current consistently exceeds the 100A rated capacity, as this would lead to nuisance tripping or potential damage to the device.
Key specifications
Number of poles: 4
Rated current: 100A
Sensitivity: 30mA
Type: A
Mounting type: DIN rail
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 all wire connections are tightened to the specified torque settings to prevent overheating and ensure optimal conductivity. Once installed, the integrated test button should be pressed to verify the mechanical operation of the tripping mechanism.
What to consider before purchase
Verify that the 100A rating is sufficient for your total circuit load
Ensure the 30mA sensitivity meets your specific safety requirements
Confirm compatibility with your existing DIN rail distribution board
Check that the 4-pole configuration matches your electrical supply system
Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the internal mechanism remains functional and responsive.
