Shop Legrand MCB DX3 6000A 1 Pole 40A Curve B Circuit Breaker | 407436 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 40A B-curve, 6kA/10kA breaking capacity, IP20 protection, and DIN rail mounting for reliable electrical installation protection.
The Legrand MCB DX3 6000A is a thermal magnetic circuit breaker specifically designed to protect wiring installations against overloads and short-circuits. This single-pole device features a 40A B-curve rating with exceptional 6kA/10kA breaking capacities, making it ideal for residential and small commercial applications. Rated for 230/400V AC operation at 50-60Hz frequency, it provides IP20 protection against solid bodies larger than 12.5mm and mounts securely on DIN rail systems.
This circuit breaker incorporates advanced protection technology with a current limiting class 3 rating according to IEC 60898-1 standard, ensuring maximum energy limitation and superior fault protection. The B-curve tripping characteristic activates between 3-5 times the rated current for short-circuit conditions, providing reliable discrimination and selective protection in electrical installations. The device features convenient on/off indication printed on the handle with red and green backgrounds for easy status identification.
The MCB DX3 is engineered with environmental consciousness, featuring halogen-free construction and compliance with substance-restriction requirements. It supports multiple connection methods including copper cables, prong busbars, fork busbars, and Legrand HX3 plug busbars. The product can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, offering flexible integration into modern electrical distribution systems. With its compact 17.8mm width and robust construction, this circuit breaker is an essential component for safe and reliable electrical protection.
