Shop Legrand DX3 MCB 3P 20A Curve D 10kA Circuit Breaker | 409500 In Iraq Best Prices
Three-pole thermal magnetic circuit-breaker with 20A D-curve rating and 10kA breaking capacity. Features IP20 protection, DIN rail mounting, and compatibility with Legrand DX3 accessories for reliable wiring protection.
The Legrand DX3 MCB 3P 20A Curve D is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 20A D-curve rating and 10kA breaking capacity at 400V~, this three-pole modular circuit breaker offers reliable protection for residential and small commercial applications. The device features IP20 terminals for fingerproof protection against solid bodies larger than 12.5mm, DIN rail mounting capability, and compatibility with Legrand DX3 auxiliaries and RCD add-on modules. The D-curve characteristic provides a tripping threshold between 200A and 280A for short-circuit protection, making it ideal for circuits with moderate inrush currents.
This MCB is equipped with two DIN rail clamps allowing independent removal while the busbar remains in place. The product includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition. It can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device is halogen-free and complies with substance-restriction requirements, designed in an environmentally conscious process.
With a rated voltage of 400V, insulation voltage of 500V, and impulse withstand voltage of 4kV, this circuit breaker meets EN 60898 and IEC 60947-2 standards. Operating temperature range is -25°C to 70°C, with storage temperature capability from -40°C to 70°C. The grey color (RAL 7035) and compact 53.1mm width make it suitable for space-constrained installations. Reference number 409500 with EAN 3414970434432 ensures product authenticity and traceability.
