JJS-500 - 500Amp Fuse Description
JJS-500 - 500Amp Fuse
When you’re working with a 500-amp fuse, getting the details right matters. The Eaton Bussmann series JJS-500 is a 500A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. For anyone replacing an existing JJS-500 or checking a fuse against equipment documentation, this model clearly defines the amperage, voltage, Class T construction, connection style, interrupting rating, and dimensions. It’s built to last, but proper selection still depends on ensuring those specifications match the requirements of the equipment where the fuse will be installed.
Key Features and Benefits
- 500A rating: Designed for applications specifically requiring a 500-amp Class T fuse.
- 600V voltage rating: Clearly defined electrical rating makes it easier to check suitability against equipment specifications.
- Class T configuration: Helps narrow down the correct fuse type when servicing equipment that specifically requires Class T protection.
- Bolted blade connections: Features a bolted blade end x bolted blade end configuration that should be matched to the equipment’s fuse mounting arrangement.
- Non-indicating design: Does not provide a built-in visual indication of fuse status.
