Residual current device with energy meter PR 304 4P 63 A, adjustable trip current 30-3000 mA, Type F (HPI), DX3 series 410657
Residual Current Device with Energy Meter – Protection and Measurement in One Device
This four-pole residual current device with energy meter, DX3 series from Legrand, combines advanced protection of electrical installations with energy consumption monitoring. Designed for operation in networks with voltage 250–440V and frequency 50Hz, it provides a reliable solution for both installers and end users. The rated current of 63A ensures safety for higher-load circuits, while the adjustable residual current range of 30–3000mA allows precise tuning to the specific requirements of the installation.
Functionality and Safety for Professionals and Users
The residual current device PR 304 features high selectivity and rapid response to short circuits and earth leakage currents. The use of characteristic C enables slower response to brief current surges, making it well-suited for starting motor-driven equipment. Protection against unwanted tripping minimizes the risk of false alarms, while the mechanical lock prevents accidental switching on or off. Additionally, the built-in energy meter enables accurate measurement of electrical energy consumption, translating into optimized operational costs.
Design and Parameters Tailored to Requirements
The housing is made from high-quality plastic, ensuring durability and resistance to mechanical damage. The IP20 protection rating guarantees safe operation under normal environmental conditions. The device is compatible with conductors of cross-section 1.5–50 mm² (single-core) and 1.5–35 mm² (multi-core). The rated impulse voltage withstand level of 6 kV ensures resistance to voltage surges. Operation across a wide ambient temperature range (-25 to 60°C) allows installation in diverse environmental conditions. The adjustable rated residual current provides flexibility to tailor protection levels—from personal safety to safeguarding sensitive equipment against disturbances.
