Shop Legrand DX3 MCB 3 Pole 1A Curve B Circuit Breaker | 407554 In Iraq Best Prices

Legrand DX3 3-pole miniature circuit breaker with 1A rating, 6000A breaking capacity, and B-curve tripping for reliable protection of residential and commercial electrical installations.

The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 6000A and B-curve tripping characteristics, this 3-pole device is ideal for residential and small commercial applications. The B-curve provides a tripping threshold between 3A and 5A (B curve between 3 In and 5 In), making it suitable for circuits with moderate inrush currents. Reference number 407554 features a rated current of 1A and operates at 400V AC, making it compatible with standard European electrical installations. This circuit breaker can be supplied through multiple connection methods including copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standard, ensuring fingerproof protection. It features maximum energy limitation (energy limitation class 3 according to IEC 60898-1 standard) and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The DX3 MCB is engineered with environmental consciousness and complies with substance-restriction requirements. It features two DIN rail clamps (top and bottom) allowing independent removal while the prong busbar remains in place. The device includes a label holder for clear circuit identification and has on/off indication printed on the handle with red and green backgrounds for easy status identification. Installation should be performed by qualified electricians in compliance with local installation rules.
