Shop Legrand MCB DX3 6000A 1 Pole 20A Curve D Circuit Breaker | 407972 In Iraq Best Prices
Single-pole thermal magnetic circuit-breaker with 20A D-curve rating, 6kA breaking capacity, and 230/400V~ operation. Includes advanced protective features, flexible installation options, and environmental compliance for residential and commercial electrical installations.
The Legrand MCB DX3 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 20A and D-curve characteristic for high inrush loads, this device is rated for 230/400V~ with a 6kA breaking capacity according to IEC 60898-1 standard. The D-curve provides a tripping threshold between 200A and 280A (10 to 14 times the rated current), making it ideal for applications with significant inrush currents such as motor loads and transformers.
This single-pole modular circuit-breaker features advanced protective capabilities and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. It offers IP20 protection against solid bodies larger than 12.5mm (fingerproof), ensuring safety in residential and commercial installations. The device can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), providing flexible installation options.
The MCB DX3 includes innovative features such as fitted DIN rail clamps for independent removal, label holder for clear circuit identification, and on/off indication printed on the handle with red and green backgrounds. It complies with substance-restriction requirements and has been designed with environmental consciousness. The product is halogen-free, rated for ambient temperatures from -25°C to 70°C, and features IK02 impact resistance. With its compact 17.8mm width and 1-modular spacing design, it integrates seamlessly into standard DIN rail installations.
