The backup current-limiting fuse installs in series with the Bay-O-Net fuse inside the padmount transformer. Its job is to clear high-current faults the expulsion fuse cannot interrupt, limiting the energy let through and preventing catastrophic failures.
We carry the Eaton Cooper Power Series line in 8.3 to 38 kV classes: partial-range backup fuses (ELSP) and full-range fuses with indoor clip mounting.
Installed in series with the Bay-O-Net expulsion fuse; they clear the high-current faults it cannot interrupt.
Clear any fault current, from minimum melt to maximum interrupting. Indoor clip mounting.
