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 component 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.

- Features
| Combination Starters, Machinery Disconnects, Motor Control Centers and Power Panelboard Applications |
| Without open fuse indication |
| 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 amp ratings that are much smaller than those of non-time delay fuses |
| Provides current limitation to help protect downstream components from high fault currents |
| Gives motor running back-up protection to motors without extra costs |
| Simplifies and improves black out prevention, offers a 10-sec time-delay at 5 times the rated current |
| Low voltage |
| Time-delay feature makes it possible to use fuse amp ratings that are much smaller than those of non-time delay fuses, considerable cost savings occur 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 cost |
