Shop Legrand MCB DX3 6000A 4 Pole 16A Curve B Circuit Breaker | 407624 In Iraq Best Prices
Professional 4-pole thermal magnetic circuit-breaker with 16A rating, 6kA breaking capacity, B-curve characteristic, IP20 finger-safe design, and DIN rail mounting for reliable electrical protection.
The Legrand MCB DX3 6000A is a professional-grade thermal magnetic circuit-breaker designed to provide comprehensive protection for wiring installations against overloads and short-circuits. This 4-pole device operates at 400V with a rated current of 16A and features a B-curve tripping characteristic with an impressive 6kA breaking capacity according to IEC 60898-1 standards. The circuit-breaker incorporates advanced energy limitation technology (Class 3) to minimize let-through energy during fault conditions, ensuring maximum protection for sensitive equipment and personnel safety.
This MCB features an IP20 finger-safe design that protects against solid bodies larger than 12.5mm, making it ideal for both industrial and commercial installations. The device comes with dual DIN rail clamps positioned on both top and bottom sides, allowing independent removal while the prong busbar remains in place. It can be supplied via copper cable, prong busbar (top or bottom side), fork busbar, or Legrand HX3 plug busbar, providing flexible installation options for various electrical configurations.
The MCB DX3 is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, enabling customized protection schemes. With its halogen-free construction and environmentally conscious design, this circuit-breaker meets all substance-restriction requirements and modern sustainability standards. The device features convenient label holders for clear circuit identification and intuitive ON/OFF indication with red and green backgrounds for easy status recognition.
