AUPO Electronics

aupoAUPO Electronics Ltd., was established in 1986 at Harbor city, Xiamen, China. AUPO is an advanced high-tech enterprise that specialized in thermal links (thermal fuses/protectors) R&D (research and development) and manufacturing. Thermal protection devices designed to protect electrical equipment from catching fire by sensing overheating, and cutting off the electrical circuit immediately. Focusing on their areas of core competency, AUPO has developed more than 10 series, 100+ models of thermal links. AUPO’s productivity achieves 1 billion pieces annually.

AUPO operates strictly under superior management system and quality assurance system ISO 9001. AUPO’s products have been recognized and certificated by a number of domestic and foreign safety laboratories including UL, CUL, VDE, TUV, CSA, PSE, KTL-EK, CCC. AUPO laboratory has been certified by UL and VDE.

Thermal fuses, Thermal cut offs

A thermal fuse, also known as a thermal limiter, thermal device, thermal cutoff, microtemp, etc., is a cutoff which uses a one-time fusible link. Unlike the thermostat which automatically resets itself when the temperature drops, the thermal fuse is more like an electrical fuse: a single-use device that cannot be reset and must be replaced when it fails or is triggered. Thermal fuses are used in many appliances such as dryers, microwaves, etc.

The thermal fuse, also called a thermal cutoff, is a small electrical switch that stops your device from heating up once it reaches its designated temperature. The thermal cutoffs (TCO) are non resetting, thermally sensitive, single pole, normally closed devices and are intended to be used in various appliances.A temperature sensitive thermal fuse melts and opens electrical contacts when temperatures exceed the rating of the thermal fuse. Thermal cutoffs are providing protection against potentially hazardous overheating conditions in billions of products around the world.

Thermal fuses or thermal cutoffs are one-time, non-resettable, temperature-sensitive devices that provides ultimate thermal protection in electrical or electronic circuits. These one-shot fuses are mainly defined by their temperature setting but also by their current rating, which is the maximum continuous current that can be applied.
