Shop Legrand DX3 MCB 2 Pole 63A B-Curve Circuit Breaker | 408948 In Iraq Best Prices
Legrand DX3 thermal magnetic 2-pole circuit-breaker with 63A B-curve rating, 10kA/16kA breaking capacity, IP20 protection, and DIN rail mounting for residential and small commercial electrical installations.
The Legrand DX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 63A and B-curve release characteristic, this 2-pole device provides a breaking capacity of 10kA at 400V and 16kA at 230V according to IEC 60898 standard. The device features IP20 finger-safe protection, making it suitable for residential and small commercial panel applications. It can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. The circuit-breaker is equipped with DIN rail clamps for easy mounting and removal, and includes a label holder for clear circuit identification.
This MCB incorporates advanced energy limitation (class 3) to minimize let-through energy during fault conditions, ensuring maximum protection for connected equipment. The device complies with all relevant EU directives including RoHS and REACH requirements, demonstrating environmental responsibility in its design and manufacturing process. It operates reliably across a wide temperature range (-25°C to +70°C) and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality.
The B-curve characteristic provides a tripping threshold between 189A and 315A (3-5 times the rated current), making it ideal for circuits with normal inrush currents typical in residential applications. With a depth of only 44mm and occupying 2 modular spacings, this compact design allows for efficient panel space utilization. The device features clear ON/OFF indication printed on the handle with red and green backgrounds for easy status identification.
