Shop Legrand DX3 MCB 1P+N 40A Curve C Circuit Breaker | 407746 In Iraq Best Prices

Legrand DX3 thermal magnetic circuit-breaker with 40A C-curve rating, 6kA breaking capacity, IP20 fingerproof protection, and DIN rail mounting for reliable residential and commercial electrical protection.

The Legrand DX3 MCB 1P+N 40A Curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This device features a 40A rated current with C-curve characteristic, providing reliable protection for residential and small commercial applications. With a 6kA breaking capacity according to IEC 60898-1 standard, this MCB is engineered for household installations where dependable circuit protection is essential. This circuit-breaker is equipped with advanced safety features including IP20 "fingerproof" protection against solid bodies larger than 12.5mm, ensuring safe operation in various environments. The device operates at 230V~ with a rated insulation voltage of 250V and impulse withstand voltage of 4kV. It features concurrently switching neutral conductor capability, allowing simultaneous disconnection of both the phase and neutral conductors for enhanced safety. The MCB can be supplied either by copper cable or prong busbar from the top or bottom side, offering flexible installation options. The product is built with DIN rail mounting capability, featuring two independent clamps (top and bottom) that allow removal without disturbing the busbar supply. It includes a label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds. The device achieves maximum energy limitation (class 3 according to IEC 60898-1) and is compatible with Legrand DX3 auxiliaries and accessories. With halogen-free construction and environmentally conscious design, this MCB meets substance-restriction requirements and offers reliable performance across operating temperatures from -25°C to +70°C.
