Operational principle
KSD-301 series use bimetal as temperature-sensitive component. In normal condition, the pair of metal sheets are in a free state with contacts being closed / disconnected state .when the temperature reaches the temperature for action, the pair will generate inner stress and move rapidly to open / close contact, switch off /on circuit, and thus playing a role in temperature control. When the electrical devices cool to the reset temperature, the contacts will automatically close / open and return to normal working condition.
