/A to 30A
inductive components, these fuses can be sized close to
full-load amps to give maximum overcurrent protection.
5.5" ( 0.31)
Permits the use of smaller and less costly switches. The
1.06" ( 0.008)
time-delay feature makes it possible to use fuse amp ratings
35A to 60A
which are much smaller than those of non-time-delay fuses.
Considerable cost saving occurs by permitting the use of
smaller size switches, panels and fuses themselves.
Provides a higher degree of short-circuit protection (greater
current-limitation) in circuits in which surge currents or
temporary overloads occur.
