Bussmann JCX Series E-Rated Medium Voltage Fuse, Class E

Bussmann JCX Series E-Rated Medium Voltage Fuse, Class E

The Bussmann JCX Series E-Rated Medium Voltage Fuse from Eaton Bussmann is a current-limiting, non-indicating fuse built for 2400V medium voltage distribution circuits. Rated Class E with a 60 kAIC interrupting rating and ferrule end to ferrule end (X) terminals, this fuse is available in amp ratings from 1A, 2A, 3A, 5A, and 7A to match a range of protection requirements across medium voltage equipment. The current-limiting element design helps reduce fault energy let-through for reliable circuit protection in demanding medium voltage electrical systems, and the single-element, non-indicating body keeps the design straightforward for compatible fuse mountings.
