Shop Legrand MCB DX3 6000A 2 Pole 4A Curve D Circuit Breaker | 408026 In Iraq Best Prices
2-pole thermal magnetic circuit-breaker with 4A D-curve rating and 6000A breaking capacity for reliable protection against overloads and short-circuits in household installations
The Legrand MCB DX3 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 2-pole device features a 4A D-curve rating specifically engineered for high inrush loads, making it ideal for applications requiring robust protection. With a breaking capacity of 6000A according to IEC 60898-1 standard, this circuit-breaker provides reliable performance in household installations. The D-curve characteristic ensures a tripping threshold between 40A and 56A (10 In to 14 In), offering superior protection against electrical faults while minimizing nuisance trips.
Beyond protection, the MCB DX3 can be used to control and isolate the installation, providing dual functionality for comprehensive electrical management. The device features a built-in depth of 44mm and is housed in a grey RAL 7035 color finish. It can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. The circuit-breaker is protected against solid bodies larger than 12.5mm with an IP20 rating according to IEC/EN 60529 standard, ensuring safety in various environments.
The MCB DX3 is equipped with two DIN rail clamps (top and bottom), allowing independent removal while the prong busbar remains in place. It features a label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds for easy status identification. Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, this circuit-breaker is halogen-free and designed with environmental consciousness. The product complies with substance-restriction requirements and can be connected to aluminum cable with terminal accessory n° 4 063 10, providing comprehensive electrical protection solutions.
