Why Choose the Mersen N217638 DIII gG Fuse Link?
The Mersen N217638 is a dependable DIN D gG screw fuse link designed to protect low-voltage cables, power lines and electrical equipment against overloads and short circuits. Identified by the catalogue number DIIIGG69V16, it combines a 16 A rated current with a 690 V AC voltage rating, making it suitable for demanding industrial and commercial distribution systems.
As part of Mersen's established D fuse-links gG series, the N217638 provides full-range overcurrent protection. Its current-limiting performance helps reduce the thermal and mechanical effects of high short-circuit currents, protecting conductors and downstream equipment while supporting reliable system operation.
Manufactured in the standard DIII DIN fuse-link size, the N217638 is suitable for compatible screw-fuse bases installed in distribution boards, switchgear and low-voltage power systems. Its grey identification colour allows the 16 A rating to be recognised quickly during inspection, maintenance and replacement.
