The two fuses are connected in series, and are coordinated so that the current-limiting fuse operates only upon internal equipment failure. FLSR series fuses Consult the Isolation link correlation chart above for the proper coordination between fuse element and isolation link. use time-current characteristic curves and specify the fuse indicated from Table 2. Edison screw (ES) is a standard lightbulb socket for electric light bulbs. If the bayonet fuse will not be used in series with a current-limiting fuse, an isolation link is required. Please wait while the characteristic curves and transformer overload curve charts are generated. Fuse rating = 1250 x 5.5 / (1.732 x 415 x 0.86) = 11.1 A. . Under oil internal arresters.
