Features and Benefits: · 2:1 selective coordination ratio (within RK5 fuse family) prevents electrical shutdowns from extending beyond the failed circuit. · Insulated end caps for 70-600A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing.
Typical Applications: · Power Panelboards · Motor Control Centers · Combination Starters · Machinery Disconnects
Note: · For superior electrical protection, Cooper Bussmann recommends upgrading FRS-R fuse applications to Low-Peak LPS-RK fuses. · For fuse reducers, please reference data sheet 1118. · *Available with optional indication. To order, place ""ID"" at the end of the catalog number. Example: FRS-R-7ID. · RK5 Dimensions: basic dimensions are same as Class H(formerly NEC) One-Time (NON & NOS) and Superlag Renewable RES & REN fuses. NOTE: These fuses can be used to replace existing Class H, RK1 and RK5 fuses relating to dimensional compatibility.
