Shop Legrand MCB DX3 6000A 2 Pole 40A Curve B Circuit Breaker | 407513 In Iraq Best Prices
Professional thermal magnetic circuit-breaker with 2-pole, 40A B-curve protection, 6kA breaking capacity, IP20 finger-safe design, and class 3 energy limitation for residential and commercial installations.
The Legrand MCB DX3 6000A is a high-performance thermal magnetic circuit-breaker designed to protect residential and small commercial wiring installations against overloads and short-circuits. This 2-pole device features a 40A rated current with B curve characteristics, delivering a 6kA breaking capacity according to IEC 60898-1 standard for household installations. The tripping threshold in case of short-circuit is precisely calibrated between 120A and 200A (B curve between 3 In and 5 In), ensuring optimal protection for critical electrical circuits.
With IP20 finger-safe protection and class 3 energy limitation, this circuit-breaker offers superior safety standards and reliable performance. The device can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), providing maximum installation flexibility. Its compact design with a built-in depth of 44mm and width of 35.4mm makes it ideal for space-constrained panel installations. The MCB is equipped with DIN rail clamps that allow independent removal while the prong busbar remains in place.
This environmentally conscious product complies with substance-restriction requirements and is halogen-free. It features a convenient label holder for circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status visibility. The device operates reliably in ambient temperatures ranging from -25°C to 70°C and supports conductor cross-sections from 1.5 to 35mm² for solid-core cables and 1.5 to 25mm² for multi-wired conductors. Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, this circuit-breaker is the ideal choice for modern electrical installations.
