Shop Legrand DX3 MCB 4P 50A D-Curve 10kA Circuit Breaker | 409538 In Iraq Best Prices
Professional 4-pole 50A D-curve circuit breaker with 10kA breaking capacity, IP20 protection, and versatile DIN rail mounting for residential and commercial electrical installations.
The Legrand DX3 MCB 409538 is a professional-grade thermal magnetic circuit breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a 50A rated current with D-curve tripping characteristic and delivers 10kA breaking capacity at 400V AC. The breaker is equipped with IP20 finger-safe protection, making it suitable for reliable DIN rail assemblies in residential and small commercial applications. The device can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), offering flexible installation options. With a built-in depth of 44mm and width of 70.8mm, it occupies 4 modular spacings on standard DIN rails.
This circuit breaker incorporates advanced safety features including concurrently switching neutral conductor capability, pollution degree 2 rating, and compatibility with Legrand DX3 auxiliaries and RCD add-on modules. The D-curve characteristic provides a tripping threshold between 500A and 700A in case of short-circuit (10 In to 14 In range), making it ideal for circuits with high inrush currents. The device is constructed with halogen-free materials and has been designed following environmentally conscious processes. It features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds for easy status identification.
The product complies with IEC 60898-1 standard for household installations and meets substance-restriction requirements. Installation should be performed by qualified electricians in compliance with local installation rules. The breaker operates reliably across a wide ambient temperature range from -25°C to +70°C and can accept multi-wired conductors from 1.5-25mm² or solid-core conductors from 1.5-35mm². With its robust construction, comprehensive protection features, and versatile mounting options, this Legrand DX3 circuit breaker represents a dependable solution for modern electrical installations.
