Legrand DX³ modular bipolar 20A circuit breaker with 25kA breaking capacity, C-curve protection, IP20 finger-safe terminals, and DIN-rail mounting for reliable electrical circuit control and protection.
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 breaker offers a rated current of 20A with a breaking capacity of 25kA at 400V, making it suitable for standard electrical installations. The device features a C-curve tripping characteristic that provides protection between 100A and 200A short-circuit currents (5In to 10In), ensuring reliable protection against electrical faults and overloads.
The DX³ breaker is equipped with IP20 finger-safe terminals that comply with IEC/EN 60529 standards, providing protection against solid bodies larger than 12.5mm. It features DIN-rail mounting with two independent clamps (top and bottom), allowing for convenient installation and removal without affecting the power supply busbar. The device can be supplied through multiple connection methods including copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexibility in installation configurations.
This circuit breaker is built with environmentally conscious design principles and complies with substance-restriction requirements. It includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. The breaker can be equipped with Legrand DX³ auxiliaries, RCD add-on modules, and various accessories to enhance functionality. With its robust construction, reliable performance, and comprehensive safety features, the DX³ 20A curve C MCB is an essential component for modern electrical installations.
