Bi-metal-Temperature switch TSA, TÖA

High operating temperatures significantly reduce the life of oils in the hydraulics and the lubrication. The prevent exceeding harmful limits, for example due to unforeseeable overloads or reduced cooling capacity, the systems must be shut off in a timely manner. This shut-off is performed using the following temperature switches TSA and TÖA.

These switches contain a bimetal that bends as the temperature rises. If the temperature exceeds a certain limit, the bimetal in- terrupts the current flow and thus protects the system from damage. After resolving the cause of the excess temperature, following a cooling phase (hysteresis) the bimetal element automatically returns to operating mode. However, for safety reasons it is advisable to still display the current oil temperat- ure on the oil tank.
