Benefits
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.
