General Information:
⢠Provides motor overload, ground fault and short-circuit pro-
tection. 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
amperes to give maximum overcurrent protection.
⢠Permits the use of smaller and less costly switches. The time-
delay feature makes it possible to use fuse ampere 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 tempo-
rary overloads occur.
⢠Helps protect motors against burnout from overloads.
⢠Gives motor running back-up protection to motors without
extra costs.
⢠Helps protect motors against burnout from single phasing on
three phase systems.
⢠Simplifies and improves blackout prevention (selective
coordination).
⢠Dual-element fuses can be applied in circuits subject to tem-
porary 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 ampere rating of the fuse for a
minimum of ten seconds.
