69T Biased Auto Reset Bimetal Control 

The 69T line of 3/4" (19mm) bimetal disc temperature controls from Therm-O-Disc® offers multiple temperature operation in a unique, cost effective design. The snap action bimetal disc provides high speed contact separation resulting in exceptional life characteristics at electrical loads up to 25 amps at 240 VAC. By utilizing heaters mounted internally, the open or close calibration of the bimetal disc can be biased lower. The more power applied to the internal heaters - the more supplemental heat is generated to bias the operating temperature of the control. The 69T is a cost effective alternative in applications where multiple temperature control is required.
