BL-301-KSD301电木

BL-WK-HKW301 series products are temperature controllers which use bimetal as temperature sensing component. 1. When the electrical appliance works normally, bimetal is in a free state, and the contacts are in a closed/open state. When the temperature reaches the operating temperature, bimetal is heated to generate internal stress and act quickly, opening/closing the contacts and cutting/connecting the circuit, thus playing a role in temperature control. When the electrical appliance is cooled to the reset temperature, the contacts will automatically close/open and return to the normal working state. 2: Manual reset requires pressing the reset button to restore the circuit.
