MECHANICAL AND ELECTRONIC CONTROLSNAP-ACTION TEMPERATURE CONTROL120A36T Snap-action temperature controlThe snap-action of the bimetal disc provides high-speed contact separation resulting in excellentlife cycle characteristics at electrical loads up to 10 Amp at 250 VAC (100.000 cycles) and(SPST) switch actions: Automatic reset (can be built to either open or close its contacts ontemperature rise). Manual reset. Single operation fuse disc.Article number Type UnitOn request 36T 200060T Snap-action temperature controlThe snap-action of the temperature sensing bimetal disc provides high-speed contact separationresulting in exceptional life characteristics at electrical loads up to 25 Amp at 240 VAC.SPDT. Manual reset SPST (trip free).Article number Type UnitOn request 60T 100037T Moisture resistant temperature controlIThe sealed design provides moisture resistance for moisture prone environments. A wideerationapplications such as defrost termination and ice cube maker control. It is also appliedin a range of heat pump and air conditioning applications. The 37T features include: sealedcontruction, high-speed contact separation ensures long contact life. All materials have beenselected to pass the refrigeration industry´s odor and taste tests.The 37T is available in two switch actions: Automatic reset SPST and automatic reset SPDT.Article number Type UnitOn request 37T 200059T / 66T Electric water heater controlsThe 59T and 66T series controls are designed to meet the high electrical capacity requirementsof electric water heaters. Both use a temperature sensitive bimetal disc to deliver snapactionto the contacts. The speed and force of contact separation provides long dependablecontrol life at high electrical loads. The 59T provides stable temperature control to all pointersettings over 43ºC adjustable range. The trip-free manual reset 66T operates at a non-adjustablefactory calibrated temperature. The 59T and 66T series features include: welded constuction,used on all internal current-carrying components for greater electical integrity. The 59Tmounting tabs snap into the customers bracket to mount the thermostat on the surface of thetank. The 66T temperature limit control is available with calibrations from 71º to 104ºC. The59T is adjustable over a range of 43ºC. Lowest calibration is 32ºC and the highest calibration is93ºC. Controls are 100% operation checked.The bimetal discs of the 59T and 66T are in intimate thermal contact with the backplates of thecontrols. Properly mounted, the 59T and 66T series controls provide good thermal response onstorage tank water heaters. The 66T function is to provide full power disconnect (through bothpower conductors) in the event of an overheat condition.NArticle number Type UnitOn request 59T / 66T 500
