Residual current device P 302 2P 25 A 30 mA Type A DX3 series 411554

Safety and Protection in Your Electrical Installation

The residual current device P 302 2P 25 A 30 mA Type A from the DX3 series is a critical component ensuring safe operation of electrical installations. Its primary function is to protect people from electric shock and to safeguard equipment against the consequences of earth faults and insulation damage. The device detects imbalances in current flow and instantly disconnects power upon detecting leakage, minimizing the risk of hazard.

Functionality and Application

This device, rated at 25 A and 30 mA sensitivity, is designed for use in 230 V AC circuits. Its Type A construction enables detection of both alternating sinusoidal currents and pulsating direct currents, making it a universal solution for most residential and professional applications. DIN rail mounting (2 module width) simplifies integration into existing electrical infrastructure. Compatibility with conductors ranging from 0.75 mm² to 50 mm² (single-core) and 0.75 mm² to 35 mm² (multi-core) ensures broad compatibility with a wide range of wiring.

Design and Key Features

The P 302 DX3 device features a robust construction and high reliability. It includes a mechanical lock that prevents accidental re-energizing after tripping due to current leakage. A built-in test button allows regular verification of device functionality, ensuring continuous protection. The enclosure is rated IP20, protecting against finger contact and ingress of solid objects larger than 12.5 mm. A short-circuit withstand rating of 10 kA guarantees resilience against sudden current surges during faults. Additionally, the device is compatible with the HX³ Optimal Energy Distribution System up to 125 A, enabling wireless connection to the electrical system. Operating temperature range from -25°C to +60°C ensures reliable performance under diverse environmental conditions.
