Legrand DX³ modular bipolar circuit breaker with 6A D-curve protection, 25kA breaking capacity, IP20 finger-safe terminals, and DIN-rail mounting for reliable electrical circuit protection
The Legrand DX³ MCB is a modular bipolar thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This device offers exceptional reliability with a 25kA breaking capacity at 400V and provides D-curve 6A protection suitable for circuits with moderate inrush currents. The breaker features IP20 finger-safe terminals for enhanced safety, preventing accidental contact with live parts. It is equipped with two DIN rail clamps allowing independent removal without disrupting the busbar supply, making it ideal for maintenance and troubleshooting in electrical panels.
The DX³ series is engineered with advanced thermal-magnetic tripping mechanisms that respond to both overload and short-circuit conditions. The device can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar from either the top or bottom, providing flexible installation options. With a built-in label holder and clear ON/OFF indication on the handle with red and green backgrounds, circuit identification and status monitoring become straightforward. The product complies with IEC 60947-2 standards and features halogen-free construction, demonstrating Legrand's commitment to environmental sustainability.
The 6A rated current with D-curve characteristic makes this circuit breaker suitable for protecting general-purpose circuits and lighting loads. Operating within an ambient temperature range of -25°C to 70°C, it maintains consistent performance across various environmental conditions. The breaker is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for system expansion and customization. Installation should be performed by qualified electricians in compliance with local electrical codes and regulations.
