Shop Legrand DX3 MCB 3 Pole 4A D Curve Circuit Breaker | 408084 In Iraq Best Prices
Thermal-magnetic 3-pole circuit breaker with 4A D-curve rating, 10kA breaking capacity at 400V, IP20 protection, and DIN-rail mounting for reliable wiring installation protection.
The Legrand DX3 MCB 6000A is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. This 3-pole, 4A D-curve device offers a 10kA breaking capacity at 400V and provides reliable control, isolation, and DIN-rail mounting capabilities. The breaker features a fingerproof design (IP20 protection) and can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar for flexible installation options.
This circuit breaker is engineered to meet IEC 60898-1 standard requirements for household installations with a breaking capacity of 6000A according to the standard. The D-curve tripping characteristic provides a short-circuit tripping threshold between 40A and 56A (D curve between 10 In and 14 In), making it ideal for protecting circuits with moderate inductive loads. The device features a convenient label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds.
The MCB DX3 is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for customizable installation configurations. With its halogen-free construction and environmentally conscious design, this product complies with substance-restriction requirements and RoHS directives. The device features two DIN rail clamps enabling independent removal while the prong busbar remains in place, and it can accommodate both multi-wired (1.5-25mm²) and solid-core (1.5-35mm²) conductors.
