This line of highly reliable switches utilize a temperature sensitive disc, electrically isolated from the switch. Contacts will open
or close on rise when surface or ambient temperature increase to the snap point of the calibrated bimetal disc. The entire switch
is enclosed in a phenolic dust-free housing. The bimetal disc is retained by a metal heat-conducting end cap.
The CA and OA Series thermostats are used in a variety of applications. They are produced in an ISO 9000 certified factory to
insure safe and reliable operation. All models are 100% factory inspected for temperature, continuity and function.
Value Added options available including over-mold and seal. For details regarding Value Added options, see page 51.
It is the customer’s sole responsibility to specify and determine the suitability of a particular
control or component based on their unique individual applications and requirements
