Product Introduction
AUPO thermal fuse is a non-resettable thermal protection component, applied for over-temperature protection of household appliances and industrial equipment. When the ambient temperature rises abnormally to a preset value, the thermal fuse senses temperature changes and cuts off the circuit.
Its fully sealed structure ensures stable and reliable fusing performance, and is not affected by harsh conditions such as moisture.
Main features: sensitive temperature sensing, accurate and stable tripping temperature, compact sealed structure and reliable performance.

* Rated Functioning Temperature (Tf)
The temperature at which a thermal fuse changes conductive state, tested in accordance with safety standard procedures.
As specified in IEC691 safety standards,
the thermal fuse must trip within the range of rated temperature +0℃ / -10℃. Abbreviated as Tf.
Actual Fusing Temperature
The melting temperature measured in a silicone oil bath at a heating rate of 0.5–1.0℃ per minute, with test current below 10mA.
This is the actual operating temperature of the thermal fuse.
Holding Temperature (Th)
The maximum temperature at which a thermal fuse can maintain conductive state for 168 hours under rated current. Expressed as Th.
Maximum Limit Temperature (Tm)
The highest temperature that a thermal fuse can withstand for 10 minutes without re-conducting. Abbreviated as Tm.
Rated Current (Ir)
Maximum current that the thermal fuse can withstand.
Rated Voltage (Ur)
Maximum operating voltage of the thermal fuse.
