The thermal cut-out with manual reset, type 162 001, is suitable for electric devices with three-phase connection, where the power supply must be interrupted permanently when the preset temperature is reached. Typical applications are e.g. hot water appliances and storage heaters.
A bimetal disc is used as a temperature sensing element. The disc is pressed directly against the mounting plate of the thermal cut-out and can therefore react quickly to changes in temperature. As soon as the preset temperature is reached, the bimetal disc operates and simultaneously opens all 3 electrical contacts. The thermal cut-out must be reset by pressing the reset tab.
