Why Choose the Mersen A081489 55GD55V6P Medium-Voltage Fuse?
The Mersen A081489, also identified as 55GD55V6P, is a high-quality medium-voltage cylindrical fuse link designed to protect compatible electrical equipment against damaging short-circuit currents. Manufactured by Mersen under the established Ferraz Shawmut range, it combines a rated current of 6 A with a rated voltage of 5.5 kV AC.
Its robust 55 × 259 mm cylindrical body is designed for installation in suitably rated medium-voltage fuse holders and switchgear assemblies. During a fault, the fuse operates rapidly to interrupt excessive current, helping limit thermal and mechanical stress on cables, transformers, switchgear and connected electrical equipment.
The A081489 also incorporates a striker mechanism, allowing compatible equipment to provide mechanical indication or initiate associated switching functions when the fuse operates. Its dependable construction and current-limiting performance make it suitable for industrial power distribution, medium-voltage controlgear and specialist electrical installations.

Dependable Medium-Voltage Circuit Protection
Medium-voltage fuse links interrupt excessive fault current before it can cause severe damage to electrical equipment. Their current-limiting operation helps restrict peak fault current and the energy passed into downstream components, reducing the thermal and dynamic effects of short circuits.
The Mersen A081489 must be selected according to the system voltage, continuous operating current, equipment inrush characteristics and prospective fault current. Compatibility with the associated fuse holder, striker system and switchgear must also be confirmed before installation.
Typical Applications
- Medium-voltage switchgear and controlgear.
- Industrial power distribution systems.
- Transformer protection assemblies.
- Medium-voltage auxiliary circuits.
- Industrial machinery and power equipment.
- Maintenance and replacement fuse applications.
