49T High Temperature Bimetal Control

The 49T series of controls from Therm-O-Disc® offers proven 3/4” (19mm) bimetal disc reliability in a high temperature package. The ceramic design of the 49T control, along with the snap action of the bimetal disc, provides exceptional life characteristics at calibrations up to 550°F (288°C) and override temperatures up to 625°F (329°C). The bimetal disc housing may be either enclosed for protection from contaminants or exposed for greater thermal sensitivity. To ensure electrical integrity, terminal connections are made with #8 terminal screws. The ability to handle electrical loads up to 25 Amps at high temperatures has made the Therm-O-Disc 49T a popular choice with heating and major appliance manufacturers.
