The fusible link mentioned here is mainly a mechanical fusible link of two metal sheets welded together with fusible alloy. It is mainly used in fire protection systems such as the triggering device in fire sprinkler systems,fire dampers and automatic door release mechanisms that close fire doors in warehouses, etc..
When the operating temperature reaches the melting point of the fusible alloy, the fusible alloy melts, the metal sheets separate, and the fire protection system starts to operate, thereby preventing the spread of fire.
It can also refer to the parts made of fusible alloys, which are used as safety device accessories in electronic and electrical appliances and household appliances.
Advantages of Fusible Link
Quick response
Fusible link is welded by low melting point alloys which can be melted quickly when reaching a certain temperature, thus cutting off the circuit or preventing further heat conduction.
Reliability
Fusible link is reliable in operation as they respond quickly to overcurrent conditions, interrupting the circuit to prevent further damage. They are a dependable form of protection in critical applications.
Compact size
Fusible link is typically compact in size, making them suitable for use in confined spaces or applications where space is limited. Their small size allows for easy integration into different systems.
Wide application
Fusible link can be machined different shape parts to suitable for work environment.Such as fire splinker,fire damper,smoke exhaust valve and so on.
Cost-effective
Fusible link is generally cost-effective compared to other types of overcurrent protection devices. They provide a simple and economical solution for protecting electrical circuits.
Easy replacement
In the event of a fault or overcurrent situation, fusible links are relatively easy to replace. This simplifies maintenance and reduces downtime in systems where they are used.

• The size of the link and the load rating in pounds for the link.
• The maximum ambient temperature rating for the link that is greater than the maximum ambient exposure temperature at the fire door. For example, an ordinary fusible link rated at 165 degrees F has a maximum ambient temperature rating of 100 degrees F. If a fusible link rated at 165 degrees F is routinely exposed to ambient temperatures over 100 degrees F, it is liable to separate and cause the fire door to close automatically. Select a fusible link rated at 212 degrees F (or greater) for this type of application.
(Note: Fusible links are available in many different load ratings. The load rating is an important factor in the design and selection of a fire protection system. Be sure to account for all loads when selecting a fusible link.)
