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.

1. Use
(H) RW 12-27 drop fuse and pull-load drop fuse are outdoor high-voltage protective appliances, which are assembled on the high-voltage side of distribution transformer or branch lines of distribution line, and are used for overload and short-circuit protection of transmission lines and power transformers and for sharing rated load current.
2. Brief introduction of structure
The drop fuse consists of two parts: insulating bracket and fuse pipe. The static contacts are installed at both ends of the insulating bracket, and the movable contacts are installed at both ends of the fuse pipe. The fuse pipe consists of an inner arc extinguishing tube and an outer epoxy glass tube. Pull-load drop fuse adds elastic auxiliary head and arc extinguishing cover to divide and close load current. When a drop fuse is in normal operation, the fuse pipe is tensioned by means of the fuse.
Then a closed position is formed. When the system fails, the fault current causes the fuse to fuse rapidly and form an arc. The arc extinguishing tube is heated by the arc and decomposes a large number of gases, which forms a high pressure in the tube and blows longitudinally along the pipeline. The arc is rapidly elongated and extinguished. After the fuse is fused, the lower moving contact loses tension and turns down. The locking mechanism releases the fuse tube, and the fuse tube falls down, forming an obvious breaking position. When the load needs to be pulled, the contact is pulled by the insulating rod. At this time, the active and static contacts are still in contact. The contacts are pulled by the insulating rod, and the auxiliary contacts are separated. Arc is generated between the auxiliary contacts. The arc is elongated in the slot of the arc extinguishing hood. At the same time, the arc is extinguished when the current passes zero.
3. Implementation criteria
The product performance conforms to GB15166.3-94 national standard and IEC282-2 international standard.
4. Conditions of Use

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.
