The Legrand DX3 residual current circuit breaker is a highly advanced protective device designed for use in commercial and industrial installations. With a rated current of 63 A and a rated residual current of 300 mA, this all-current sensitive circuit breaker provides a reliable solution for detecting fault currents, including alternating, pulsating, and smooth direct fault currents. It meets the stringent requirements of the standards VDE 0664-10, VDE 0664-11, VDE 0664-40, as well as EN 61008-1 and EN 61008-2-1. The breaker is designed for frequencies ranging from 0 Hz to 1 kHz and offers high operational safety through a time-delayed tripping mechanism that minimizes false tripping. With a robust construction and the ability to be mounted on a DIN rail, this residual current circuit breaker is ideal for applications in areas such as photovoltaic systems, air conditioning units, medical devices, and construction sites. The clear switching position indicator and labeling window ensure user-friendly handling.

• All-current sensitive residual current circuit breaker for various fault currents
• Complies with multiple international standards for safety and reliability
• High tripping threshold to reduce false tripping
• Suitable for use in demanding industrial applications
