Bussmann (821) FRS-R-50 50A FRS-R SERIES TIMe DELAY, DUAL-ELEMENT, CURRENT LIMITING FUSE

Eaton Bussmann Series Class RK5 fuse, FRS-R, time-delay, dual-element, current limiting fuse, 50 A, non-indicating fuse, interrupting rating of 200 kA at 600 Vac and 20 kA at 250 Vdc. These cartridge fuses are 23% more energy efficient and offer the best time-delay performance. Their dual-element feature allows closer sizing to load for superior protection of motors and transformers. These Class RK5 fuses with a 200 kA interrupting rating can be used in a broad range of applications. When sized correctly, they help protect motors from burnout caused by overloads or single-phasing. The time-delay feature allows the initial startup current surge for typical motors to pass, but opens prior to motor burnout when longer, dangerous overloads are present. In addition, the dual-element design opens in as little as 0.004 second if the fuse experiences short-circuit conditions. All fuses are UL Listed Class R (IR: 200 kA)
