AGA-20

Fuses are electrical safety devices designed to protect electrical circuits and equipment from electrical over current or overload by interrupting high current flow. The AGA-20 is a thermal fuse, also known as a thermal cut off device. It is a resettable fuse with a built-in heat-sensitive thermistor that is designed to open the circuit when the ambient temperature around the device exceeds a predetermined level. This article will focus on the AGA-20 application field and its working principle.The AGA-20 is usually installed in a wide variety of products and applications. A few typical applications are listed below:

• Domestic appliances – washing machines, dishwashers, refrigerators and freezers
• Office equipment – printers, photocopiers, computers and fax machines
• Small electrical tools – drills, saws, sanders and iron
• Small household appliances – vacuum cleaners, microwaves, kettles and toasters
• Consumer electronics – radios, TVs and DVD players

The AGA-20 is designed to provide efficient and reliable over temperature protection when mounted in a wide range of products and applications.The AGA-20 is a resettable fuse powered by a thermal cut off device. It works with a heat-sensitive thermistor that is designed to open the circuit when the ambient temperature of the junction area exceeds a predetermined level.When the AGA-20 is installed, it senses the ambient temperature of the junction area. If the temperature exceeds the set level, the thermistor will become hotter, expand in size and increase its conductance. This increase in current will cause the thermistor to become even hotter. This will result in an open circuit. This reverse flow of current will stop the flow of current across the device, thus preventing further damage to the circuit and equipment.Once the temperature of the junction area has dropped below the predetermined level, the thermistor will cool down and reduce its conductance. This decrease in current will cause the thermistor to return to its normal size and the circuit will be closed again.The use of the AGA-20 provides several advantages over traditional fuses, such as:

• It is capable of providing efficient and reliable over temperature protection
• The AGA-20 is a resettable fuse, so it does not need to be replaced after every overload
• It is much more reliable and durable than traditional fuses
• It does not require an external power source
