New bussmann frs-r-90 fuse
Product Information BUSSMANN Fuses - UL Class RK5 Item# FRS-R-90 FRS-R Series Information
* Cartridge or Single Slotted
Bussmann FRS R series fuses provide 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 amperes to give maximum overcurrent protection. The grooved ring in the ferrule and the slot in the knife blade, when used in conjunction with special fuseholders designed to accept Class R fuses only, prevent accidental interchanging of any other fuse class.
* Simplifies and Improves Blackout Protection
* Protects Motors From Burnout From Overloads
* Protects Motors From Burnout From Single Phasing on 3 Phase Systems
