Shop Legrand DX3 MCB 4P 2A Curve D 10kA Circuit Breaker | 409526 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker with 4-pole, 2A D-curve, 10kA breaking capacity at 400V, and IP20 finger-safe protection for residential and commercial wiring installations.
The Legrand DX3 MCB 10000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a 2A rated current with D-curve characteristic and 400V~ rating, delivering reliable protection for residential and small commercial applications. It offers an impressive 10kA breaking capacity at 400V and IP20 finger-safe protection, ensuring safe operation in various electrical environments. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, providing flexible installation options for different panel configurations.
This circuit breaker is engineered with advanced safety features including thermal and magnetic protection mechanisms that respond to both gradual overloads and sudden short-circuits. The D-curve characteristic provides a tripping threshold between 20A and 28A for short-circuit protection, making it ideal for circuits with higher inrush currents. Built with two DIN rail clamps on top and bottom, the device allows independent removal without affecting the busbar supply. The product complies with IEC 60898-1 standard for household installations and features halogen-free construction, reflecting Legrand's commitment to environmental responsibility.
The MCB includes practical features such as a label holder for circuit identification, ON/OFF indication on the handle with red and green backgrounds for easy status recognition, and compatibility with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. With a built-in depth of 44mm and width of 70.8mm, it fits standard DIN rail installations. The device operates reliably across ambient temperatures from -25°C to 70°C and includes enhanced protection against electrical surges with a rated impulse withstand voltage of 4kV.
