In electrical distribution, a fuse cutout or cut-out fuse 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 melt, disconnecting the transformer from the line. It can also be opened manually by utility linemen standing on the ground and using a long insulating stick called a "hot stick". Wholesale Fuse Cutout â??s Construction The fuse elements used in most distribution cutouts are tin or silver alloy wires that melt when subjected to high enough current. Ampere ratings of fuse elements vary from 1 ampere to 200 amperes. Standards Up until the mid-1990s each manufacturer used their own dimensional standards for cutout design; by the late 1990s most cutouts were of an "interchangeable design". This design allows for the interchangeable use of cutout bodies and fuse holders manufactured by different vendors.

Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current. The drop fuse is composed of two parts: An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer. It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the load current.

The drop out fuse switch is an overcurrent protector, which is mainly composed of melt, fuse tube, and external fillers. When used, the drop out type fuse needs to be connected in series in the circuit to be protected. When the current of the protected circuit exceeds the specified value and after a certain period of time, the heat generated by the melt itself fuses the melt and disconnects the circuit, thus playing a protective role. Drop out fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As short circuit and overcurrent protectors, they are one of the most commonly used protection devices. The drop out fuse element has inverse delay characteristics, that is, when the overload current is small, the fusing time is long; when the overload current is large, the fusing time is short. Maintenance of Power Quality By swiftly disconnecting faulty circuits, drop out fuse cutouts contribute to maintaining power quality in the distribution system. This is important for ensuring a stable and reliable power supply to consumers. Easy Replacement Overcurrent Protection Drop out Fuse Application Distribution Transformers Drop-out fuses are commonly installed on the primary side of distribution transformers. These drop out type fuses provide overcurrent protection to the transformer against faults such as short circuits and overloads. In the event of a fault, the drop out fuse in transformer opens, isolating the transformer from the faulted section of the circuit.

Fuse Cutout Specification: A fuse cutout or cut-out fuse 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.

High quality Electrical Fuse

Thermal fuse manufacturing The thermal fuse is a non-resettable, one-time overheat protection element, and the current fuse is a one-time overcurrent protection element. Series connection in a variety of electrical power input, when the use of household appliances in the abnormal temperature changes, or temperature out of control lead to excessive temperature rise, the thermal fuse can quickly cut off the circuit to avoid the occurrence of fire. Commonly used in: hair dryer, iron, rice cookers, electric stoves, transformers, motors, drinking fountains, coffee pots and so on.
