inductive components, these fuses can be sized close to

full-load amps to give maximum overcurrent protection.

• Permits the use of smaller and less costly switches. The

time-delay feature makes it possible to use fuse amp ratings

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.

(selective coordination)

• Dual-element fuses can be applied in circuits subject to

temporary motor overloads and surge currents to provide

both high-performance, short-circuit and overload

protection

• The overload element provides protection against low level

overcurrent of overloads and will hold an overload which is

five times greater than the amp rating of the fuse for a

minimum of ten seconds
