Bipolar Temperature Control Thermal Switch KSD303 For High Power Machinery

 Bipolar Temperature Control Thermal Switch KSD303 For High Power Machinery Equipment

KSD303 series bipolar thermostat’s Principle and structure

KSD303 is a bimetal thermostat temperature component, electric work; sheet metal in a free state, the contact is closed / disconnected state when the temperature reaches operating temperature, the bimetallic thermal stresses generated within the tables and rapid movements, open/closed contacts OFF/ON circuit, and thus play areole in temperature control. When the electrical cooling to reset temperature, the contacts automatically closed / opens, to restore normal operation.
