Overview

The Mersen B217742 DIN D0 Fuse-link Neozed gG is a high-reliability fuse designed for low-voltage distribution systems. Rated for 400VAC and 250VDC, this 20A fuse-link (color-coded blue) is part of the standardized D02 size (E18 thread) within the Neozed D0 system. Engineered for general application, it protects cables, power lines, and equipment from overcurrents and short-circuit currents up to its nominal breaking capacity. The gG utilization category ensures full-range breaking capacity, providing comprehensive protection against dynamic effects of high short-circuit currents. With a power dissipation of 2W at rated current, it maintains thermal stability in demanding environments. The D0 system is IEC-compliant and designed for accessibility by non-trained personnel, allowing safe replacement in low-voltage distribution units. Compatible with D0 fuse-bases, this fuse-link is ideal for industrial, commercial, and utility applications where reliable overcurrent protection is critical. Packaged in quantities of 50, it offers cost-effective bulk availability for large-scale installations.
