JJS-90 - 90Amp Fuse Description
JJS-90 - 90Amp Fuse
When you’re checking a replacement fuse, the useful details are the ones that remove uncertainty. The Eaton Bussmann series JJS-90 is a 90A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. For facilities, electricians, and maintenance teams trying to identify the correct JJS-90 fuse without digging through unnecessary marketing language, these specifications make the decision easier. The fuse is also CE-marked and RoHS-compliant. It’s built to last, but proper application still requires confirming the full electrical and physical specifications before installation.
Key Features and Benefits
- 90A rating: Clearly rated at 90 amps for equipment requiring this specific fuse amperage.
- 600V Class T fuse: Combines a 600-volt rating with the manufacturer-specified Class T designation for straightforward specification matching.
- Rejection-style design: The manufacturer identifies rejection style as a special feature of the JJS-90.
- Bolted blade connections: Uses a bolted blade-to-bolted blade configuration, an important detail when confirming physical compatibility.
- Non-indicating: The JJS-90 does not incorporate a built-in visual fuse-status indicator.

Where It Works Best
The JJS-90 90A 600V Class T fuse is best suited to compatible electrical equipment that specifically calls for its combination of a 90A rating, 600V rating, Class T designation, 200 kAIC interrupting rating at 600VAC, rejection-style configuration, and bolted blade connections. Also check the documented dimensions, especially when selecting the JJS-90 for existing equipment where physical fit matters alongside the electrical ratings.
