3-pole thermal magnetic circuit-breaker with 16A rated current, B curve, 6kA breaking capacity, IP20 protection, and DIN rail mounting for residential and commercial electrical installations.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 3-pole device features a rated current of 16A with B curve characteristics, operating at 400V with a breaking capacity of 6kA according to IEC 60898-1 standard and 10kA according to IEC 60947-2. The circuit-breaker incorporates advanced current limiting technology (Class 3) to minimize let-through energy, ensuring maximum protection for electrical systems. With IP20 protection rating, it is fingerproof against solid bodies larger than 12.5mm and features DIN rail mounting for easy installation and removal.
This MCB is equipped with dual DIN rail clamps positioned on both top and bottom sides, allowing independent removal even when the prong busbar remains in place. The device supports multiple connection methods including copper cables, prong busbars, fork busbars, and Legrand HX3 plug busbars. It features a convenient label holder for circuit identification and clear ON/OFF status indicators on the handle with red and green backgrounds respectively. The product is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, making it highly versatile for residential and small commercial panel installations.
The circuit-breaker operates reliably across a wide temperature range (-25°C to +70°C) and features halogen-free construction, demonstrating environmental consciousness in its design. With a tripping threshold between 48A and 80A for short-circuit conditions (B curve between 3In and 5In), this device provides reliable protection while minimizing nuisance trips. The product complies with all substance-restriction requirements and has been certified through multiple international standards including VDE, CB, and OC certifications.
