Residual current device P 304 4P 80 A 30 mA type F (HPI) DX3 series 411697

Protection and Safety in Your Electrical Installation

This four-pole residual current device (RCD) from Legrand’s DX3 series is a critical component ensuring personnel safety and fire protection in electrical installations. Designed for operation at 400V and rated current of 80A, it effectively detects leakage currents, protecting against electric shock and damage caused by earth faults. Its construction based on proven HPI (High Performance Immunity) technology ensures immunity to electromagnetic interference, minimizing the risk of unwanted tripping—especially in environments with elevated electromagnetic disturbance levels.

Versatility and Compatibility

The P 304 4P breaker offers a wide range of applications. It can be mounted on a DIN rail, simplifying integration into existing distribution boards. It accepts both single-core cables (up to 50 mm²) and multi-core cables (up to 35 mm²), providing flexibility in cable selection. Additionally, it is compatible with the HX³ Optimal Power Distribution System up to 125A, enabling wireless connection to electrical systems. Expandability with auxiliary contacts and trip units enhances functionality and allows customization to meet specific installation requirements.

Robust Construction and Reliability

Designed for durability and reliability, this breaker features a mechanical lock that prevents accidental re-energizing after tripping due to RCD activation. Its enclosure is rated IP20, protecting against finger contact and ingress of solid objects larger than 12.5 mm. With a short-circuit withstand rating of 10 kA, it ensures proper operation even under high fault current conditions. It complies with EN 61008-1 standards, confirming conformity with European safety requirements. The F sensitivity setting ensures effective operation in the presence of leakage currents typical of electronic devices and LED lighting.

• Module width: Compact dimensions (4 modules) enable easy installation even in crowded distribution boards.
• Operating temperature: Wide operating temperature range (-25°C to +60°C) allows use both indoors and in outdoor enclosures.
• Impulse current protection: High impulse current resistance (3 kA) ensures durability and reliability under harsh operating conditions.
• Cable connections: Supports both single-core cables (up to 50 mm²) and multi-core cables (up to 35 mm²), offering great installation flexibility.
• Testing: Built-in test button enables regular verification of RCD functionality—essential for maintaining continuous installation safety.
