Bimetal Disc-Type Thermostats
Circuit Loads
The ability of disc-type controls to handle loads is due to the fact they operate strictly on changes in temperature and are designed to be isolated from the circuit current. In disc-type devices, there is no internal heating effect of the bimetal element because of the electrical load passing through the bimetal element. For this reason disc type controls are often more suitable than other controls for resistive current loads above six amps. This includes many common applications in products such as coffee makers and hot water heaters.
