Overview

The Mersen K206365 is a robust 3-pole DIN fuse base designed for the Neozed D0 fuse system, specifically engineered for low-voltage distribution units operating in 400VAC/250VDC networks. This D02 size fuse base is ideal for applications where fuse-links are accessible and replaceable by non-trained personnel, adhering to German DIN standards. It provides essential protection for cables and power lines by working in conjunction with D0 fuse-links, which effectively limit and cut off unacceptable overcurrents and short-circuit currents up to their nominal breaking capacity. This ensures protection for equipment and installations against the dynamic effects of high short-circuit currents. The K206365 features screw mounting with clamp strap and screw terminals, accommodating cable cross-sections from 1.5 to 25 mm². It is rated for 400VAC and a maximum current of 63A, with 3 poles for three-phase applications. This model does not include touch protection, making it suitable for installations where direct contact is managed. Manufactured by Mersen, a trusted name in electrical protection, this fuse base (SKU: K206365) is built for reliability and performance in industrial and commercial electrical distribution systems. Its design facilitates straightforward installation and maintenance, contributing to operational safety and efficiency. The D0 fuse-system represents the newest generation of screw fuse systems within the German DIN standard, offering a dependable solution for critical power protection needs.
