Residual current device P 302 2P 63 A 300 mA type AC, DX3 series 411526

Safety and Protection in Your Electrical Installation

This two-pole residual current device (RCD) from the DX³ series is a critical component ensuring safety in every electrical circuit. It protects people from electric shock and safeguards the installation against the consequences of earth faults, minimizing fire risk. The rated residual current of 300 mA, combined with AC characteristic, makes it an ideal solution for protecting circuits with higher impedance where disturbances may occur.

Construction and Installation

The P 302 2P switch, with a width of only 2 modules, easily fits into any distribution board thanks to its compact dimensions (35.6 mm x 94.8 mm x 77.8 mm). Installation is performed on a standard DIN rail, ensuring quick and hassle-free mounting for both professionals and experienced DIY enthusiasts. Screw-type terminals guarantee secure and durable connections for conductors with cross-sections ranging from 0.75 mm² to 50 mm² (single-core) or 0.75 mm² to 35 mm² (multi-core). Additionally, the device features a lock that prevents accidental re-energizing after tripping due to protective activation.

Specifications and Applications

The switch features a rated voltage of 230 V and a rated current of 63 A. With a short-circuit withstand capacity of 10 kA, it ensures reliable operation even during high transient overvoltages. The device complies with standard NF EN 61008-1 and has an IP20 protection rating, providing protection against finger contact and foreign objects larger than 12.5 mm in diameter. The operating ambient temperature range is from -25°C to +60°C, enabling use in diverse environmental conditions. It is equipped with a test button allowing regular verification of its functionality—a simple step to confirm proper operation of the shock protection system. Additionally, the device is compatible with the HX³ Optimal Power Distribution system and Legrand DX³ auxiliary accessories, enhancing its functionality and adaptability to individual installation requirements.
