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.
