Time-delay affords the same excellent overload protection as low peak fuses of motors and other type loads and circuits having temporary inrush currents such as those caused by transformers and solenoids. (In such circuits, Limitron fuses can only provide short circuit protection). Fusetron fuses are not as Fast-Acting on short circuits as low peak fuses and therefore cannot give as high a degree of componet short circuit protection. Like the low peak fuse, Fusetron fuses permit the use of smaller size and less costly switches. Fusetron fuses fit rejection type fuse holders and can also be installed in holders for Class H fuses. They can physically and electrically replace Class H, K5, and other Class RK5 fuses.

| Ind Facilities & Factories - Facility: Safety and Security Systems |
| Renewable |
| Dual element feature provides the best time delay performance, allowing closer sizing and superior protection of motors and transformers |
| Closer sizing allows for smaller fuses and less costly switches |
| Class RK5 fuses with a 200 kA interrupt rating for use in a broad range of applications |
| Provides motor overload, ground fault and short circuit protection |
| Helps protect motors against burnout from overloads and single phasing when sized properly |
| 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 |
| Offers a 10 sec time delay at 5 times the rated current |
| The time delay feature makes it possible to use fuse amperage 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 current limitation to help protect downstream components from high fault currents |
| Gives motor running back up protection to motors without extra costs |
