Shop Legrand DX3 MCB 1 Pole 25A D-Curve Circuit Breaker | 409434 In Iraq Best Prices
Single-pole thermal-magnetic circuit breaker with 25A D-curve rating, 10kA/16kA breaking capacity, IP20 finger-safe protection, and DIN rail mounting for residential and small commercial installations.
The Legrand DX3 MCB 10000A is a high-performance thermal-magnetic circuit breaker designed to protect residential and small commercial wiring installations against overloads and short-circuits. With a rated current of 25A and D-curve release characteristic, this single-pole breaker offers reliable protection with a breaking capacity of 10kA according to IEC 60898-1 standard and 16kA according to IEC 60947-2. The device features IP20 finger-safe protection, preventing accidental contact with live parts larger than 12.5mm. Built with DIN rail mounting capability and equipped with two independent clamps (top and bottom), it allows convenient removal without disturbing the main busbar supply. The breaker can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options.
This circuit breaker is engineered with advanced thermal-magnetic tripping technology that responds instantly to short-circuits (250A-350A tripping threshold) while providing gradual thermal protection against overloads. The D-curve characteristic makes it ideal for general purpose circuits with moderate inrush currents. The device includes a convenient label holder for circuit identification and features clearly marked ON/OFF positions on the handle with red and green backgrounds for easy status identification. Compatible with Legrand DX3 auxiliaries and RCD add-on modules, it provides comprehensive installation flexibility and future expandability.
Manufactured with halogen-free materials and designed through environmentally conscious processes, the DX3 MCB meets all relevant safety standards including RoHS and REACH compliance. Operating safely across a wide ambient temperature range of -25°C to +70°C, with storage capability from -40°C to +70°C, this breaker is suitable for diverse installation environments. The product carries a carbon footprint of 0.904 kg CO₂ equivalents during the manufacturing phase, reflecting Legrand's commitment to sustainable electrical solutions.
