Thermal magnetic 3-pole 40A circuit breaker with 10kA breaking capacity, C curve protection, DIN rail mounting, and fingerproof IP20 design for residential and commercial installations.
The Legrand DX3 MCB 3 Pole 40A Circuit Breaker with C curve is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This device features a 10kA breaking capacity at 400V~ and provides reliable protection with C curve tripping characteristics between 5In and 10In. The MCB can also be used to control and isolate the installation, making it an essential component for residential and small commercial electrical systems.
This circuit breaker is equipped with two DIN rail clamps (top and bottom) allowing independent removal while the prong busbar remains in place. It features fingerproof protection (IP20 according to IEC/EN 60529) against solid bodies larger than 12.5mm and offers maximum energy limitation in class 3 according to IEC 60898-1 standard. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, providing flexible installation options.
The DX3 MCB is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, offering expandable functionality. It complies with substance-restriction requirements and has been designed in an environmentally conscious process. The device includes a convenient label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification.
