Shop Legrand DX3 MCB 1 Pole 40A Curve C Circuit Breaker | 407674 In Iraq Best Prices
Single pole 40A thermal magnetic circuit breaker with 6kA/10kA breaking capacity, C curve protection, IP20 fingerproof design, and DIN rail mounting for residential and small commercial installations
The Legrand DX3 MCB 1 Pole 40A Curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This high-performance device features a 40A rated current with C curve characteristics, providing a tripping threshold between 200A and 400A for short-circuit protection. With a breaking capacity of 6kA according to IEC 60898-1 standard and 10kA according to IEC 60947-2, this circuit breaker ensures reliable protection for household and small commercial installations.
The DX3 MCB incorporates advanced protection features including IP20 fingerproof design, protecting against solid bodies larger than 12.5mm. It features maximum energy limitation (energy limitation class 3 according to IEC 60898-1 standard) and can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar. The device includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition.
This circuit breaker is equipped with two DIN rail clamps (top and bottom) allowing independent removal while the prong busbar remains in place. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The product complies with substance-restriction requirements and has been designed in an environmentally conscious process, featuring halogen-free construction. Operating temperature range is -25°C to 70°C, with storage temperature capability from -40°C to 70°C.
