Mersen / Ferraz Shawmut A155F2D0R0-125E Medium Voltage E-Rated Ferrule Mount Fuse

Mersen / Ferraz Shawmut A155F2D0R0-125E 15.5 kV E-Rated Ferrule Mount Fuse

The Mersen A155F2D0R0-125E is a medium-voltage, E-rated current-limiting fuse from the Amp-Trap® CS-3 series. It is designed for transformer protection applications requiring controlled overload response and high interrupting capability in indoor or enclosed installations.

Fuse Design and Protection Characteristics

• E-rated performance in accordance with IEEE C37.42.
• Current-limiting operation to reduce fault energy.
• Non-venting construction for silent operation.
• Visual blown-fuse indicator for status identification.

Mechanical Configuration

This fuse uses a ferrule-mounted design compatible with standard spring-reinforced clips. The dual-barrel construction and 3-inch diameter body support installation in medium-voltage transformer protection assemblies.

Typical Applications

• Indoor transformer primary protection.
• Medium-voltage distribution systems in enclosed equipment.
• Applications requiring E-rated current-limiting protection.
