LS Thermal Switch Type 34 to 50 Amperes
Thermal switches simultaneously protect motors against short circuits and overloads. In the event of a short circuit or overload, thermal switches disconnect the electric motor from the power source. In other words, these switches operate like overload relays or bimetals but can be manually turned on and off.
The operation of this switch is based on the difference in the linear expansion coefficient of two metals used. When current passes through the bimetal, the two metals heat up and lengthen. Since one metal has a higher linear expansion coefficient than the other, the two metals bend toward the metal with the lower linear expansion coefficient. As a result, the current path contacts open and the circuit is disconnected. Alongside thermal switches, auxiliary equipment including auxiliary contacts, fault contacts, shunt coils, and undervoltage coils are used. Given that these switches can protect against short circuits, they have different short-circuit breaking capacities depending on the operating current range.
