In this ar range ment, secondary faults and overload currents are cleared by the Bay-O-Net fuse, and high level faults are cleared by the current-limiting fuse. For 1/10-30 amperes, order non-indicating FLNR series fuses. In general, the current-limiting fuse should only operate for internal faults in the transformer. Summary of overcurrent protection for less than 600V. The dual-element design provides advanced short circuit and overload protection. a. fuse (Catalog CA132013EN) is recommended in series with the Bay-O-Net link.

FLNR_ID / FLSR_ID SERIES INDICATOR FUSES 250/600 Vac Dual Element Time Delay 1/ 10-600 A Description Available in both Indicating and Non-Indicating versions, the FLNR/FLSR series of fuses set the standard for general purpose fuses. This fuse is also used in field refusible bushings, such as those used on pole-type and livefront pad-mounted transformers. 0000042900 00000 n
According to the chart above, 16.67 amps is in the range of the top row, 9 amps or more, so the overcurrent protection should be 125% of the primary full load current. 0000006965 00000 n
per your comment, what other details are needed for the calculation? 0000020242 00000 n

In this arrangement, secondary faults and overload currents are cleared by the Bay-O-Net fuse, and high level faults are cleared by the current-limiting fuse. All transformers equipped with a BAYONET fuse should also be equipped with an isolation link, as a safety feature. All Rights Reserved. 0000024700 00000 n
