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 amperes to give maximum over current 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 in circuits 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
