Fuses consist of a fuse base and a fuse link: With the fuse base, an isolating distance can be established when the fuse link is pulled out in de-energized condition (like in a disconnector). The fuse link is used for one single breaking of a short-circuit current.
Transformers, high-voltage motors and other consumers must be protected against thermal and dynamic overloads resulting from short-circuits in order to avoid consequential damages.
HV HRC (high-voltage high-rupturing capacity) fuse-links type 3GD are especially adequate in order to protect devices and switchgear sections, as the standardized fuse characteristics are adapted to the interaction between the different protection equipment. They are suitable for indoor and outdoor switchgear, operation with high humidity and frequently changing condensation. You’ll find detailled informations in the download on the right site.
3GH fuse base
No matter whether high humidity or occasional condensation, HV HRC (high-voltage high-rupturing capacity) fuse-bases control these environmental conditions in indoor switchgear without any problems. They are available as single-pole versions (3GH1) and three-pole versions (3GH3) for rated voltages from 7.2 kV to 36 kV. You’ll find detailled informations in the download on the right site.
