In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. Bay-O-Net fuses can be used on single-phase conventional and self-protected distribution transformers and on three-phase equipment. 0000007595 00000 n 0000034667 00000 n Bay-O-Net fuses are compa rable in cost to internal cartridge fuses but have the advan tages of being field-replaceable. 0000029748 00000 n endstream endobj 11 0 obj <> endobj 12 0 obj <>/Rotate 0/Type/Page>> endobj 13 0 obj <> endobj 14 0 obj <> endobj 15 0 obj <> endobj 16 0 obj <>stream 11.0 0000024657 00000 n characteristics that are easier to coordinate with existing protective devices, such as boric acid fuses, reclosers and power fuses.
