Why Choose the Mersen W097815 Medium-Voltage Fuse-Link?
The Mersen W097815, also identified as FR20GC155C2 and 20GC155V2, is a cylindrical medium-voltage fuse-link designed to protect potential transformers, voltage transformers and other low-power receptors against damaging overcurrents and short-circuit faults. Its compact construction provides dependable circuit protection in specialised medium-voltage installations.
Manufactured by Mersen, formerly known as Ferraz Shawmut, the W097815 uses current-limiting fuse technology to interrupt fault currents rapidly. This helps reduce the thermal and dynamic stresses imposed on protected equipment, supporting reliable operation and limiting the risk of extensive damage during an electrical fault.
With a rated voltage of 15.5 kV AC, a rated current of 2 A and a cylindrical 20 × 254 mm format, this fuse-link is particularly suited to low-current medium-voltage circuits. Its end-cap design allows installation in a compatible inline fuse holder or fuse base within indoor switchgear and distribution equipment.

Reliable Protection for Low-Power Medium-Voltage Equipment
Potential transformers and other low-power medium-voltage receptors require appropriately rated fuse protection to isolate faults before excessive current damages windings, conductors or connected switchgear. The Mersen W097815 provides rapid current-limiting operation while maintaining a compact form suitable for specialised fuse assemblies.
Its 15.5 kV voltage rating and low 2 A current rating make it particularly suitable for voltage measurement, auxiliary supply and instrumentation circuits. Correct fuse selection should always consider the equipment operating current, system voltage, transient conditions and the requirements of the associated fuse holder.
Typical Applications
- Potential transformer protection.
- Voltage transformer circuits.
- Low-power medium-voltage receptors.
- Medium-voltage measurement and metering systems.
- Auxiliary power circuits within switchgear.
- Industrial and utility electrical distribution equipment.
