General Information:
• Provides motor overload, ground fault and short-circuit pro-
tection. When used in circuits subject to surge currents such
.81" ( 0.008)
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
1.06" ( 0.008)
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.
