FRS-R-250 Application
Combination Starters, Machinery Disconnects, Motor Control Centers and Power Panelboard Applications, Safety and Security SystemsFRS-R-250 Item 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 over current protection
- 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 savings occur by permitting the use of smaller size switches, panels and fuses themselves
- Provides a good deg 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 cost
- Helps protect motors against burnout from overloads and single phasing when sized properly
- Simplifies and improves blackout prevention (selective co-ordination 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
