Features:
•
Provides motor overload, ground fault
and short-circuit protection. When used in
circuits subject to surge currents such as
those caused by motors, transformers and
other inductive components, these fuses
can be sized close to full-load amps to give
maximum overcurrent protection
•
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 good degree of short-circuit
protection (greater current-limitation) to help
protect downstream components from high
fault currents
•
Gives motor running back-up protection to
motors without extra cost
•
Helps protect motors against burnout from
overloads and single-phasing when sized
properly
•
Simplifies and improves blackout prevention
(selective coordination ratios)
•
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
