Shop Legrand DX3 MCB 3 Pole 20A Circuit Breaker B-Curve | 408992 In Iraq Best Prices

Professional-grade thermal magnetic circuit breaker with 10kA breaking capacity, 20A B-curve protection, and advanced safety features for reliable wiring installation protection.

The Legrand DX3 MCB is a thermal magnetic circuit breaker designed to provide comprehensive protection for wiring installations against overloads and short circuits. With a breaking capacity of 10kA at 400V, this 3-pole device delivers reliable performance with a 20A B-curve characteristic, offering superior energy limitation in class 3. The device features DIN-rail mounting for easy installation and can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections. This circuit breaker is engineered with advanced safety features including IP20 protection against solid bodies larger than 12.5mm, making it fingerproof and compliant with IEC/EN 60529 standards. The unit supports a wide range of conductor cross-sections from 1.5mm² to 35mm² for solid-core wiring and 1.5mm² to 25mm² for multi-wired conductors. Its modular design allows for independent removal even when the busbar is energized, thanks to dual DIN rail clamps positioned on both top and bottom sides. The product incorporates Legrand's environmentally conscious design principles and is halogen-free, complying with RoHS and REACH regulations. It features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds. The device operates reliably across a wide temperature range from -25°C to +70°C and maintains its integrity with a carbon footprint of 2.980 kg CO₂ equivalent during the manufacturing phase.
