Shop Legrand DX3 MCB 1P 4A B-Curve 10kA Circuit Breaker | 408868 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker with 1-pole, 4A B-curve rating, 10kA breaking capacity, IP20 protection, and DIN rail mounting for residential and commercial electrical installations.
The Legrand DX3 MCB 10000A is a thermal magnetic circuit-breaker designed to protect and isolate wiring installations against overloads and short-circuits. This 1-pole device features a 4A B-curve rating with a 10kA breaking capacity at 230V, providing reliable protection for residential and small commercial electrical systems. The circuit-breaker is IP20 finger-safe protected, meeting IEC/EN 60529 standards, and offers energy limitation class 3 according to IEC 60898-1 standard. It features dual DIN rail clamps allowing independent removal while the busbar remains in place, and includes a convenient label holder for circuit identification. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, and is compatible with DX3 auxiliaries and RCD add-on modules.
This MCB is engineered with advanced thermal-magnetic protection characteristics, featuring a B-curve tripping threshold between 3 In and 5 In for short-circuit protection. The release characteristic provides optimal protection for standard residential wiring installations. With its compact 1-module width design and 44mm built-in depth, it integrates seamlessly into DX3 distribution panels. The device includes ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Built from halogen-free materials and designed with environmental consciousness, this circuit-breaker complies with all substance-restriction requirements and RoHS directives.
The Legrand DX3 MCB is suitable for connecting solid-core conductors between 1.5-35mm² or multi-wired conductors between 1.5-25mm². Operating temperature range extends from -25°C to 70°C, with storage capability from -40°C to 70°C. The device features a screwed terminal connection type and is rated for 50-60 Hz frequency operation. With its proven reliability, comprehensive certifications including VDE and CB-IT standards, and compatibility with Legrand's extensive DX3 accessory range, this circuit-breaker represents a complete protection solution for modern electrical installations.
