Why Choose the Mersen A219719 DIIIGG69V50 DIN D Fuse-Link?
The Mersen A219719 is a dependable DIN D fuse-link designed to protect low-voltage cables, power lines and electrical equipment against overload and short-circuit currents. Identified by the manufacturer reference DIIIGG69V50, this fuse-link has a 50 A current rating and a full-range gG operating characteristic.
Designed for the established Diazed screw-fuse system, the A219719 uses the standard DIII fuse size and features white current-rating identification. Its robust ceramic body provides reliable electrical insulation and thermal resistance, making it suitable for demanding industrial and commercial electrical installations.
With a rated voltage of 690 V AC, the Mersen A219719 is suitable for higher-voltage low-voltage distribution systems. When installed in a compatible DIII fuse base with the correct gauge component and screw cap, it provides effective current limitation and reliable protection against damaging fault currents.

Reliable Protection for DIN D Electrical Systems
DIN D fuse-links interrupt excessive electrical current by melting their internal fuse element when an overload or short circuit occurs. This rapidly disconnects the affected circuit and limits the thermal and dynamic stress imposed on cables, conductors and connected equipment.
The gG characteristic of the Mersen A219719 provides full-range protection against both overload and short-circuit currents. Its 690 V AC rating makes it particularly suitable for compatible industrial distribution systems requiring a higher operating voltage than standard 500 V fuse installations.
Typical Applications
- Low-voltage industrial distribution boards.
- Electrical switchgear assemblies.
- Cable and power-line protection.
- Commercial and industrial power systems.
- Machinery and automation control panels.
- DIII Diazed screw-fuse installations.
