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.
• 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.
• 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
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
