BOLTED TAG 25A 63LET FUSE

Product Description

The 63LET is a high-speed, current-limiting bolted-tag fuse from the Eaton Bussmann LET series. It is designed for rapid interruption of short-circuit faults while withstanding high fault levels in industrial electrical systems. Its bolted tag construction allows secure mounting on fuse bases or busbar systems, making it suitable for switchgear, distribution panels, and control assemblies.

This fuse is known for its very fast operating characteristic (FF type), making it ideal where sensitive equipment requires immediate fault isolation.
