Shop Legrand DX3 MCB 1P 1A B-Curve 6kA Circuit Breaker | 407425 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 1A rating, B-curve characteristic, and 6kA breaking capacity. Features IP20 protection, DIN-rail mounting, and compatibility with Legrand DX3 series accessories.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 1A and B-curve characteristic, this single-pole breaker provides a breaking capacity of 6kA at 230V, making it ideal for residential and small commercial applications. The device features IP20 protection against solid bodies larger than 12.5mm (fingerproof design) and is mounted on DIN rails for easy installation and removal. Reference number 407425 with EAN 3245064074254 ensures authentic Legrand quality and compatibility with the DX3 series ecosystem.
This circuit breaker incorporates advanced protection mechanisms with a tripping threshold for short-circuits between 3A and 5A (B-curve between 3In and 5In), providing optimal protection for sensitive circuits. 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 current limiting class 3 according to IEC 60898-1 standard, this MCB delivers maximum energy limitation for enhanced safety.
The DX3 MCB is equipped with two DIN rail clamps (one top, one bottom) allowing independent removal while the busbar remains in place. It features a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, this breaker is halogen-free and designed with environmental consciousness. The device complies with all substance-restriction requirements and should be installed by qualified electricians in accordance with local installation rules.
