Key Features
High-Speed Circuit Protection
Designed for applications requiring a high-speed fuse, subject to the fuse’s published operating characteristics and the equipment manufacturer’s specifications.
175A Current Rating
The 175A rating helps identify the correct fuse size for a circuit design. It does not, by itself, establish suitability for every 175A application.
Stud-Mounted Connection
The fuse uses a stud-mounting arrangement. Check terminal dimensions, mounting centres and connection requirements against the existing equipment before replacement.
Non-Indicating Design
The listed product is non-indicating. Do not assume it has a visual fuse-status indicator.
Typical Applications
Depending on the electrical design and manufacturer’s guidance, high-speed fuses may be used in:
– Power electronic equipment
– Industrial electrical systems
– Power conversion equipment
– Compatible high-speed fuse assemblies
– Systems requiring coordinated protection of sensitive components
