Legrand 411971

The DX3 residual current circuit breaker from Legrand is a highly advanced protective device specifically designed to detect fault currents in the frequency range of 0 Hz to 1 kHz. With a rated current of 40 A and a rated residual current of 300 mA, this 4-pole switch provides a reliable solution for various applications, including photovoltaic systems, pumping and ventilation systems, as well as construction site power distributions. The switch is all-current sensitive and is suitable for both alternating and direct fault currents. Its short-time delay tripping and high tripping threshold ensure increased operational safety, reducing the likelihood of false tripping. Installation is straightforward on DIN rails according to the EN 60715 standard, and the user-friendly labeling window allows for clear indication of the switch positions. The DX3 residual current circuit breaker is thus a valuable component for the safety of electrical installations.
