JJS-40 - 40Amp Fuse

JJS-40 - 40Amp Fuse

A replacement fuse is easier to evaluate when the important details are right in front of you. The Eaton Bussmann series JJS-40 is a 40A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. If you’re maintaining existing electrical equipment that calls for JJS-40—or a fuse with these exact electrical and physical requirements—this gives you the essential details needed to check compatibility without sorting through unnecessary marketing language. It’s built to last, while proper selection still depends on confirming the fuse class, ratings, dimensions, connection style, and requirements of the equipment being serviced.

Key Features and Benefits

• 40A Class T fuse: Provides the specified 40-amp rating for compatible equipment requiring a Class T fuse.
