Shop Legrand MCB DX3 6000A 1 Pole 3A Curve B Circuit Breaker | 407427 In Iraq Best Prices
Legrand MCB DX3 6000A single-pole 3A circuit breaker with B curve protection, 6kA breaking capacity, IP20 fingerproof rating, and DIN rail mounting for residential and commercial electrical installations.
The Legrand MCB DX3 6000A is a high-performance thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with a 6kA breaking capacity and B curve characteristic. This single-pole device is rated at 3A with 230V nominal voltage and is engineered to control and isolate electrical installations safely and reliably. The breaker features a modern design with DIN rail mounting capability, fingerproof IP20 protection, and energy limitation class 3 according to IEC 60898-1 standard.
This MCB is equipped with two DIN rail clamps positioned on the top and bottom sides, allowing independent removal while the prong busbar remains in place. 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). It features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds respectively. The product complies with all substance-restriction requirements and has been designed following environmentally conscious manufacturing processes.
With a built-in depth of 44mm and width of 17.8mm, this compact breaker integrates seamlessly into residential and small commercial panel installations. It supports connectable conductor cross-sections from 1.5-25mm² for multi-wired cables and 1.5-35mm² for solid-core conductors. The device operates reliably within ambient temperatures ranging from -25°C to 70°C and features a rated short-circuit breaking capacity of 10kA according to IEC 60947-2, providing superior protection for modern electrical systems.
