Legrand DX³ modular 2-pole 25A circuit breaker with 25kA breaking capacity, C-curve protection, and DIN rail mounting for residential and small commercial electrical circuits
The Legrand DX³ MCB (Miniature Circuit Breaker) is a modular bipolar thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This 2-pole 25A device operates at 230/400V~ AC with a breaking capacity of 25kA according to IEC 60947-2 standards. The C-curve tripping characteristic (5In to 10In) provides optimal protection against short circuits with a tripping threshold between 125A and 250A, making it ideal for general purpose circuits with moderate inrush currents.
The DX³ series features visible breaking for clear status indication, with on/off positions printed on the handle in red and green backgrounds for easy identification. The device is IP20 rated (fingerproof protection against solid bodies larger than 12.5mm) and can be mounted on DIN rail with two independent clamps allowing removal even when the busbar is energized. The circuit breaker accepts copper cables, prong busbars, fork busbars, or Legrand HX3 plug busbars for flexible installation options, with connectable conductor cross-sections ranging from 1.5-25mm² (multi-wired) to 1.5-35mm² (solid-core).
This environmentally conscious product complies with substance-restriction requirements and includes a label holder for circuit identification. The DX³ can be equipped with Legrand auxiliaries, RCD add-on modules, and various accessories to expand functionality. With an operating temperature range of -25 to 70°C and storage capability from -40 to 70°C, this reliable circuit breaker delivers consistent performance in diverse installation environments. The device features a compact 35.4mm width, 94.8mm height, and 77.8mm depth with a built-in depth of 44mm for space-efficient panel mounting.
