JJS-20 - 20Amp Fuse Description
JJS-20 - 20Amp Fuse
When your electrical equipment calls for a 20-amp Class T fuse, the amperage is only one piece of the compatibility puzzle. The Eaton Bussmann series JJS-20 is a 20A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. The JJS-20 is non-indicating and features a rejection-style design, both important characteristics when identifying the correct fuse for compatible equipment. CE-marked and RoHS-compliant, this compact fuse is built to last while keeping the selection process grounded in what really matters: the right fuse class, ratings, connection style, and physical fit.
Key Features and Benefits
- 20A Class T configuration: Combines a 20-amp current rating with the manufacturer-specified Class T designation for straightforward identification.
- 600V rating: Suitable for equipment specifically designed to use a fuse with this voltage rating.
- Ferrule-to-ferrule connection: Uses a ferrule end-to-ferrule end configuration, an important physical characteristic to verify when replacing an existing fuse.
- Rejection style: The manufacturer identifies the JJS-20 as a rejection-style fuse, providing another useful detail for determining application compatibility.
- Non-indicating design: Does not incorporate a built-in visual fuse-status indicator.

Where It Works Best
The JJS-20 20A 600V Class T fuse is a practical choice for compatible electrical equipment that specifically requires a 20A Class T fuse rated at 600V with a 200 kAIC interrupting rating at 600VAC. Confirm applications that require its ferrule-to-ferrule connection, rejection-style configuration, non-indicating design, and 1.50 x 0.56 x 0.56-inch dimensions.
