LS Bimetal Type MT-32/3H (7-10)
The bimetal switch is used to protect electric motors and other electrical equipment against overcurrent. The construction of this switch consists of two dissimilar metals that have different coefficients of linear expansion and are pressed together in a cold state. The operation of the bimetal switch is such that when the current passing through exceeds the nominal current (overcurrent), the temperature rises, causing the length of the two metals to increase. Since the two metals are different, they bend. This action causes the circuit to open or close.
Manual bimetals, after operating and opening the circuit, cool down and return to their initial state; however, the contacts that have changed position remain in that state. To reconnect, the reset button on the bimetal must be pressed manually so that the contacts return to their original position and the circuit is ready for reconnection. This type of bimetal is used in systems where their control circuits are either automatic or non-automatic.
Automatic bimetals, when a fault (overload) occurs in electrical systems, open the relevant circuit through a closed contact and, after a certain cooling period, the contacts return to their original state. This type of bimetal is used in systems where the control circuit is manually operated, such as star-delta starting circuits of three-phase electric motors, overhead cranes, hoists, industrial machines, electric bending machines, guillotines, presses, and more.
Bimetal manufacturers, to avoid excessive product variety, do not produce manual and automatic bimetals separately. Instead, both types are combined into one unit and a switch provided on it is used to change modes.

The bimetal is selected based on the nominal current of the electrical device or the current passing through the location where the bimetal is installed. Because the current drawn by electrical devices, especially electric motors under different loads, varies. Therefore, to choose a suitable bimetal, determine the current flowing through the installation location and select the bimetal within the nominal current range and adjust it exactly to the nominal current (flowing current).
