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.

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.

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. We not only related to the product structure and technology, more in-depth to the core of the product - Fuse materials development and application, such as fusible alloy wire, lead antimony alloy wire, organic mixture and so on. To provide you with one-stop from the rapid proofing to small batch production services. Please contact our professional team, let us come for you to achieve all the technical requirements. What Is A Thermal Fuse? Thermal fuse, is overheat protection components, also known as temperature fuse or Thermal Cutoff (GB GB1616.1-2013), widely used in electrical overheating protection. The temperature sensing portion can be divided into:Fusible alloy wire and organic particle type temperature fuse, after fusing once cut off the current, non-recovery type thermal fuse.

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. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to melt, disconnecting the transformer from the line.

Specifications: Ratings Volts - 500 Vdc Amps 50-400 A Interrupting rating Max DC 20 kA Min DC 200% Agency information Designed to: JASO D622 ISO 8820-8 Manufactured under a TS16949 quality system for compliance with automotive requirements RoHS compliant REACH declaration available upon request Packaging 20 mm fuses: 250 fuses per box 25 mm fuses: 100 fuses per box 30 mm fuses: 100 fuses per box Features: Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the needs of higher voltage battery packs. Higher interrupting rating protects high capacity battery packs needed for vehicle acceleration and range requirements. Up to ten times faster opening under high fault current conditions helps assure reliable protection of circuits and components. Requires up to 48% less space than conventional high speed fuses to help reduce space and weight. Data logging system marks each fuse with a serial number and date code for traceability of Critical to Quality characteristics. To help project the life of the fuse in your application, unique driving profiles and conditions can be simulated to verify proper fuse size and performance under a wide range of driving behaviors. Operation as low as 200% overload provides back up protection to the battery management system. Can be applied in parallel to realize greater ampacity within sizing guidelines.
