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 ...
In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. [1] The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices.
A cylinder fuse is a type of electrical fuse.Like other types of fuses, it is a safety device used to protect electrical devices from excessive current. [1] [2]As its name suggests, a cylinder fuse is shaped like a cylinder.

Connectors on this cable would be designated:
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 ...
More fixes, the blade on the side view of the low-profile mini fuse was converted from a rectangle to a path. 11:19, 7 May 2017: 870 × 520 (83 KB) Havarhen: Some minor fixes: 10:54, 7 May 2017: 870 × 520 (83 KB) Havarhen: Fixed a small drawing mistake on the low-profile mini fuse, as reported by User:Sbmeirow: 17:09, 30 September 2014: 870 × ...
A pencil detonator or time pencil is a time fuze designed to be connected to a detonator or short length of safety fuse. They are about the same size and shape as a pencil , hence the name. They were introduced during World War II and developed at Aston House , Hertfordshire , UK .
A black match is a type of fuse consisting of cotton string coated with a dried slurry of black powder and glue. This acts as a simple pass-fire, and was used to fire ancient cannons. They are used today in fireworks construction. A quick match or piped match is a type of black powder fuse that burns very quickly, some hundreds of feet per ...
