FRS-R-7 Application
Combination Starters, Machinery Disconnects, Motor Control Centers and Power Panelboard Applications, Safety and Security SystemsFRS-R-7 Item Features
- 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 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
