JJS-250 - 250Amp Fuse Description
JJS-250 - 250Amp Fuse
Don't bury the important details when you're checking a replacement fuse. The Eaton Bussmann series JJS-250 is a 250A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. For electricians, facility teams, and maintenance personnel working with equipment that requires these characteristics, the JJS-250 makes essential compatibility details easy to identify. It's built to last, while proper selection still comes down to confirming the documented electrical ratings, connection style, dimensions, and equipment requirements.
Key Features and Benefits
- 250A Class T fuse: Clearly defined 250-amp rating makes it easier to compare the JJS-250 with the requirements of the equipment being serviced.
- 600V voltage rating: Suitable for equipment specifically designed to use a fuse with this voltage rating.
- Bolted blade connection: Features a bolted blade-to-bolted blade configuration, an important physical detail when determining compatibility.
- Non-indicating configuration: It does not include a visual fuse-status indicator.

The Eaton Bussmann JJS-250 is best suited for compatible electrical equipment that requires a 250A, 600V Class T fuse with a 200 kAIC interrupting rating at 600VAC. Its bolted blade-end x bolted blade-end connection and 3.63 x 1 x 1-inch dimensions are equally important when checking whether the fuse matches the equipment's required physical configuration.
