Shop Legrand MCB DX3 10000A 3 Pole 40A Curve D Circuit Breaker | 409503 In Iraq Best Prices

Professional 3-pole 40A thermal magnetic circuit-breaker with 10kA breaking capacity, D-curve protection, and IP20 finger-safe design for reliable wiring installation protection

The Legrand MCB DX3 10000A 3 Pole 40A Curve D is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This professional-grade device features a 10kA breaking capacity at 400V~ with D-curve tripping characteristics, making it ideal for residential and small commercial applications. The 3-pole configuration with 40A rated current provides reliable protection for three-phase electrical systems with comprehensive overload and short-circuit defense. This circuit-breaker is equipped with advanced safety features including IP20 finger-safe design that prevents accidental contact with live parts. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. With a breaking capacity of 10kA according to IEC 60898-1 standard, it provides exceptional protection with a tripping threshold between 400A and 560A (D curve between 10 In and 14 In). The MCB DX3 is equipped with DIN rail clamps allowing independent removal while the prong busbar supplying the row remains in place. It features 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. The device complies with substance-restriction requirements and has been designed in an environmentally conscious process, making it suitable for modern electrical installations.
