Fuses and electrical protection symbols.

Thermal cut out symbol.

Fuses are devices containing a small piece of special wire that melts when the intensity of the current flowing through it for a certain period of time exceeds a set value thus protecting the rest of the electrical circuit overloads. Thermal fuse 10a 250v 228c 442f 480. The term thermal cutoff switch generally refers to how the switch is used ie. It cuts off the current to critical machinery when a temperature limit is exceeded preventing potential burn out or failure.

A thermal fuse is a cutoff which uses a one time fusible link unlike a thermal switch which may automatically reset itself when the temperature drops the thermal fuse is more like an electrical fuse. They operate as a sensitive power cut out for both single and three phase motors. New products are added daily so check back frequently. Use scheme it s comprehensive electronic symbol library and an integrated digi key component catalog to design and share electronic circuit diagrams.

The applications of and need for electromechanical thermal switch devices are broad and cover a huge diversity of industry applications. Zebra builds enterprise level data capture and automatic identification solutions that provide businesses with operational visibility. In single phase motors up to a given motor size around 1 1 kw it can be mounted directly in the main circuit to serve as an on winding protector.
