Shop Legrand DX3 3 Pole 6A Curve D Circuit Breaker MCB | 409831 In Iraq Best Prices
Three-pole modular thermal-magnetic circuit breaker with 6A D-curve rating, 25kA breaking capacity at 400V, IP20 finger-safe design, and DIN rail mounting for reliable electrical circuit protection.
The Legrand DX³ is a three-pole modular thermal-magnetic circuit breaker designed for comprehensive control, protection and isolation of electrical circuits in residential and small commercial applications. This advanced MCB offers a robust 25kA breaking capacity at 400V~ with a 6A D-curve performance specification, ensuring reliable protection against short-circuits and overloads. The device features an IP20 finger-safe design that protects against solid bodies larger than 12.5mm, making it safe for installation in accessible locations. With DIN rail mounting capability and two independent clamps (top and bottom), this circuit breaker allows for easy installation and removal without disrupting the prong busbar supply.
The DX³ MCB incorporates advanced thermal-magnetic tripping technology with a D-curve characteristic, providing a tripping threshold between 60A and 84A in case of short-circuit (D curve between 10 In and 14 In). The device is engineered for compatibility with multiple supply methods including copper cables, prong busbars (top or bottom side), fork busbars, and Legrand HX3 plug busbars. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories to enhance functionality and adaptability to different installation requirements.
Built with environmental consciousness and compliance with substance-restriction requirements, the DX³ features a halogen-free construction and a carbon footprint of 2.891 kg CO₂ eq. during the manufacturing phase. The circuit breaker operates reliably across a wide ambient temperature range of -25°C to 70°C and supports connectable conductor cross-sections from 1.5mm² to 35mm² for solid-core cables or 1.5mm² to 25mm² for multi-wired conductors. Its grey RAL 7035 color finish and clear labeling system with red/green handle indicators provide excellent visual identification of circuit status and protection.
