Residual current device with energy meter PR 304 4P 125 A, adjustable trip current 30-3000 mA, Type F (HPI), DX3 series 410658

Advanced protection and metering in one device

The PR 304 4P 125A residual current device with energy meter is a reliable solution for electrical installations requiring both protection and energy consumption monitoring. This device combines the functions of a Type F RCD with a precise energy meter, enabling comprehensive control over safety and energy efficiency. Designed for 4-pole systems with a rated current of 125A, it performs excellently in residential, commercial, and industrial applications.

Functionality and flexibility

This residual current device stands out with an adjustable residual current range from 30 to 3000 mA, ensuring flexibility to adapt to specific installation requirements. The adjustable sensitivity minimizes the risk of unnecessary tripping. Additionally, the time delay setting allows customization of the tripping characteristic according to load type. The integrated energy meter provides valuable data on energy consumption, aiding in cost optimization and identification of potential savings.

Safety and durability

The design of the PR 304 residual current device prioritizes maximum operational safety. It features an IP20 protection rating, safeguarding against contact with solid foreign objects larger than 12.5 mm in diameter. Withstand capability up to 6 kV impulse voltage ensures resistance to sudden voltage surges. The device also includes a mechanical lock to prevent accidental opening or closing of the circuit. Designed to operate in a wide temperature range (-25°C to +70°C) and compliant with pollution degree 3, it guarantees reliable performance even under harsh environmental conditions. Protection against unintended tripping further enhances user comfort. The ability to connect conductors with cross-sections from 1.5 mm² to 70 mm² (single-core) or from 1.5 mm² to 50 mm² (multi-core) simplifies installation and integration into existing electrical systems.
