Thermorex TK34A

Bimetallic temperature sensitive switch or cyclic operation device with automatic reset control.

THERMOREX TK34A

This device operates with the automatic reset option. Further variations of this device are the TK34M with the manual reset option, and the TK34R with the resistance based internal heater. This thermostat can be used in high current applications (up to 45A). This thermostat can be built to either open or close its electrical contacts as the temperature increases. Once the temperature of the bimetal disc has returned to the specified reset temperature, the contacts will automatically return to their original state. Besides its variety of standard configurations the thermostat can also be customized to Your specific technical needs, assuring maximum design flexibility and usage in broad range of temperature control applications for consumer, industrial and commercial products.

ApplicationNote
