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 costs.
• 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.
