OPERATIONA rise in temperature causes the expansion of liquid within the bulb and capillary. The liquid acts on a bellows assembly within the plastic housing to open and close electrical contacts with temperature variation. In case of abnormal rise in temperature, liquid expansion in a separate bulb capillary assembly will break independent contacts to insure safety operation. The limiter is manually resettable.
