† Gould, Westinghouse and General Electric are General Purpose Fuses.
Current-limiting medium voltage fuses are classified into three categories:
Full Range - defined by ANSI as “a fuse capable of interrupting all currents from the maximum rated interrupting current down to
the minimum continuous current that causes melting of the fusible element(s), when the fuse is applied at the maximum ambient
temperature specified by the manufacturer.” It is able to interrupt any normal 60 cycle current that will melt its element.
General Purpose - defined by ANSI C37.40 as “a fuse capable of interrupting all currents from the maximum rated interrupting
current down to the current that causes melting of the fusible element in one hour.” Not all currents fall within this range. It is
possible to receive an overcurrent lower than the value given by the one hour criterion.
Back-up - defined by ANSI C37.40 as “a fuse capable of interrupting all currents from the maximum rated interrupting current
down to the rated minimum interrupting current.” The minimum rated interrupting current is the lowest current that the fuse will be
able to clear properly. This creates a need to place a low current interrupting device in series with the back-up rated fuse.
All Bussmann MV series medium voltage fuses are E-rated and offer Full Range Protection.
The only controlled copy of this Data Sheet is the electronic read-only version located on the Bussmann Network Drive. All other copies of this BIF document are by definition uncontrolled.This bulletin is intended to clear-
ly present comprehensive product data and provide technical information that will help the end user with design applications. Bussmann reserves the right, without notice, to change design or construction of any prod-
ucts and to discontinue or limit distribution of any products. Bussmann also reserves the right to change or update, without notice, any technical information contained in this bulletin. Once a product has been selected,
it should be tested by the user in all possible applications.
