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. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...
NH fuses of sizes 000 and 00, rated 63A and 125A NH fuses of sizes 1, 2 and 3, rated 250A, 400A and 630A NH fuses [ 3 ] have a square or oblong body and blade-style terminals. These fuses are larger and have higher ratings than the screw type fuses, exceeding 100 kA.
An assortment of thermal fuses. A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).
BS 1362 specifies sand-filled ceramic-bodied cylindrical fuses, with dimensions of 1 in (25 mm) in length, with two metallic end caps of 1 ⁄ 4 in (6.4 mm) diameter and roughly 1 ⁄ 5 in (5.1 mm) long. The standard specifies breaking time versus current characteristics only for 3 A or 13 A fuses.
UL 248-1 sets the general requirements for fuses, while the latter parts are dedicated to specific fuses sizes (ex: 248-8 for Class J, 248-10 for Class L), or for categories of fuses with unique properties (ex: 248-13 for semiconductor fuses, 248-19 for photovoltaic fuses).
On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts. For example, on a wye to delta conversion, when cutouts are used on the wye side and only 1 out of 3 of the cutout fuses open, some customers on the delta side have a low voltage condition, due to voltage transfer through the transformer windings. Low voltage ...
