Residual current device P 304 4P 25 A 30 mA type F (HPI) DX3 series 411694

Safety and Protection in Your Electrical Installation

This four-pole residual current device (RCD) from the DX³ series is a critical component ensuring safety in every circuit. Designed to protect against electric shock and prevent fires caused by earth faults, it provides a reliable barrier against potential hazards. The P 304 model, with a rated current of 25A and 30mA sensitivity, type F (HPI), performs exceptionally well in both residential and industrial installations where high reliability and operational effectiveness are required.

Functionality and Applications

The P 304 RCD, thanks to its design and parameters, delivers comprehensive protection. Type F (HPI) features enhanced immunity to interference, minimizing the risk of unwanted tripping in environments with elevated levels of electromagnetic noise. DIN rail mounting (TH35) simplifies integration into existing electrical infrastructure. The ability to expand with additional accessories—auxiliary contacts, trip units—allows customization of functionality to meet specific installation requirements.
