Why Choose the Mersen N081478 Medium Voltage Fuse?
The Mersen N081478, manufacturer reference 55GD55V80P, is an 80 A medium voltage cylindrical fuse-link designed to protect public lighting networks and specialist electrical distribution equipment. Its current-limiting performance helps interrupt damaging fault currents before they can place excessive thermal and mechanical stress on connected equipment.
Part of Mersen's proven medium voltage protection range, the N081478 combines a robust cylindrical body with an integrated striker mechanism. The striker can provide mechanical indication or operate compatible switchgear when the fuse-link has interrupted a fault, helping maintenance teams identify and isolate affected circuits.
With a rated voltage of 5.5 kV AC, a rated current of 80 A and a 55 × 259 mm body size, this gLD fuse-link is particularly suited to public lighting infrastructure and other medium voltage systems requiring reliable fault protection and dependable service continuity.
