One-shot Low Resistance Compact Size AUPO Thermal Cutoff Fuse Link Tf 130℃ 250V 5A A4-5A-F With Globally Certified Temp
Upper Limit Temperature Protection
Aupo thermal fuse, the original thermal fuse from Therm-O-Disc, offers the broadest combination of globally certified temperatures and electrical loads, as well as the broadest range of packages, mountings and design confi gurations on the market today.
Features
• Globally certifi ed temperatures and electrical loads
• One-shot operation cuts off electrical power
• Current interruption capacity up to 25 amps @ 250VAC
• Low resistance
• Compact size
• RoHS compliant,UL,CUL,CCC,KTL,PSE,VDE
Operating Principle
The active trigger mechanism of the thermal fuse is an exclusively formulated, electrically nonconductive pellet. Under normal operating temperatures, the solid pellet holds spring loaded contacts closed. When a predetermined temperature is reached, the pellet melts, allowing the compression spring to relax. The trip spring then slides the contact away from the lead and the circuit is opened.
After the thermal fuse opens a circuit, the fuse needs to be replaced. This replacement procedure must include correction of the fault condition before the product is operated again.

Important Notice
Users must determine the suitability of the thermal fuse for their application, including the level of reliability required,and are solely responsible for the function of the end-use product.These thermal fuses contain exposed electrical components and are not intended to withstand exposure to water or other environmental contaminants which can compromise insulating components. Such exposure may result in insulation
breakdown and accompanying localized electrical heating.
A thermal fuse may remain permanently closed or open as a result of exposure to excessive mechanical, electrical, thermal or environmental conditions or at normal end-of-life. Failure to control the operation could result in personal injury or property damage. The user should incorporate supplemental system control features to achieve the desired level of reliability and safety. For example, backup temperature limiting devices have been incorporated in a number of applications for this reason.
