The thermostat combination 161 751 is suitable for controlling or monitoring two fixed temperatures. Typical applications are e.g. ovens, steam generators and washing machines.

Bimetal discs are used as temperature sensing elements. The discs are pressed directly against the mounting plate of the combination and can therefore react quickly to changes in temperature. As soon as the individual preset temperatures are reached, the bimetal discs operate and open (or close) the electrical circuit. On cooling the discs snap back into the original position closing (or opening) the circuit again.

Advantages

• easy mounting
• two components on a base plate with homogeneous heat transfer
• high contact pressure and low contact resistance
• orientation-independent switching behavior
• fast response time, suitable for high performance and low-mass heating elements
• robust ceramic-housing with separated switching chamber
• high strength even after many switching cycles
• stable switching temperature even with different current load
• defined temperature drift over service life (optionally available)
