Shop Legrand DX3 MCB 3 Pole 63A D-Curve 10kA Circuit Breaker | 409505 In Iraq Best Prices
Professional 3-pole thermal magnetic circuit breaker with 63A rating, D-curve protection, and 10kA breaking capacity. IP20 finger-safe protection with DIN rail mounting and comprehensive accessory compatibility.
The Legrand DX3 MCB 10000A is a professional-grade thermal magnetic circuit breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 63A and D-curve release characteristic, this 3-pole breaker delivers a breaking capacity of 10kA at 400V~. The device features IP20 finger-safe protection, ensuring safe operation in residential and small commercial applications. Built with precision engineering, it provides reliable control and isolation of electrical installations with exceptional safety standards.
This circuit breaker is equipped with two DIN rail clamps for independent removal while the prong busbar remains in place. The device supports multiple supply methods including copper cable, prong busbar (top or bottom side), fork busbar, and Legrand HX3 plug busbar connections. It incorporates a convenient label holder for circuit identification and clear ON/OFF indication on the handle with red and green backgrounds respectively. The breaker is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it a versatile solution for modern electrical installations.
Designed with environmental consciousness, this product complies with substance-restriction requirements and RoHS directives. The thermal magnetic protection mechanism ensures rapid response to fault conditions, with short-circuit tripping thresholds between 630A and 882A (D-curve between 10In and 14In). Operating across a wide temperature range from -25°C to +70°C, it delivers consistent performance in diverse environmental conditions. The grey RAL 7035 colored housing provides a professional appearance while maintaining durability and reliability in demanding electrical environments.
