Shop Legrand DX3 MCB 1P 20A B-curve 6kA Circuit Breaker | 407433 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 20A capacity, 6kA breaking capacity, B-curve characteristic, and IP20 protection for residential and small commercial wiring installations
The Legrand DX3 6000A MCB is a thermal magnetic circuit breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability. This single-pole 20A B-curve breaker delivers a 6kA breaking capacity at 230V and features energy limitation class 3 according to IEC 60898-1 standard. The DX3 series represents advanced protection technology for residential and small commercial applications, offering fingerproof IP20 protection and compatibility with multiple supply methods including copper cables, prong busbars, fork busbars, and Legrand HX3 plug busbars.
This circuit breaker is engineered with dual DIN rail clamps positioned at the top and bottom, enabling independent removal while the prong busbar remains in place. The device features a convenient label holder for clear circuit identification and includes ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition. With a rated voltage of 230V and insulation voltage of 500V, it provides robust protection across standard electrical installations. The B-curve tripping characteristic responds between 60A and 100A during short-circuit conditions, making it ideal for general-purpose circuits.
Manufactured with environmental consciousness, this product complies with substance-restriction requirements and RoHS directives. The grey-colored housing (RAL 7035) provides durability and professional appearance in any installation. Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, the unit can be connected to aluminum cables using appropriate terminal accessories. With halogen-free construction and a carbon footprint of 0.847 kg CO2 eq., this breaker combines safety, reliability, and environmental responsibility.
