Residual current device P 304 4P 25 A 100 mA type AC, series TX3 411717

Safety and Reliability in Your Installation

The residual current device (RCD) P304 is a critical component ensuring protection of people and equipment in electrical installations. The device effectively responds to leakage currents, minimizing the risk of electric shock and preventing fires. This model, with a rated current of 25A and sensitivity of 100mA type AC, is ideal for both new installations and upgrades of existing systems.

Design and Installation – Enhanced Comfort for Professionals

The P304 from the TX³ series features a thoughtfully designed construction that simplifies wiring and installation. The bottom clip and shielded terminals significantly ease the installer’s work. Mounting is performed on a standard DIN rail, ensuring compatibility with most distribution boards. Compact dimensions—4 modules wide and 44 mm deep—allow optimal space utilization in the distribution cabinet. Compatibility with auxiliary devices (auxiliary contacts, trip units) further enhances system functionality.

Parameters Tailored to Your Needs

This four-pole (4P) RCD, rated at 400V, is designed to protect circuits with currents up to 25A. Type AC sensitivity indicates response to sinusoidal alternating differential currents, typical for most residential and industrial loads. The rated differential current of 100mA ensures effective protection while minimizing unnecessary tripping. With a short-circuit withstand capacity of 10kA, the device guarantees reliable operation during fault conditions. Additionally, the device features a mechanical lock that prevents accidental re-energizing after tripping. The connected conductor cross-section ranges from 0.75…50 mm² for single-core and 0.75…35 mm² for multi-core cables.

• Compliance with Standards: The device meets the requirements of EN 61008-1, confirming its safety and quality.
• Wide Operating Temperature Range: The device maintains performance in temperatures from -25°C to +60°C.
• High Immunity to Interference: IP20 protection rating guards against finger contact and ingress of solid objects larger than 12mm.
• Expandability: Compatibility with DX³ series accessories allows customization of the device’s functionality to meet specific installation needs.
• Test Button: Built-in test button enables regular verification of the RCD’s proper operation.
