hotrelayModel list

hotrelayby the inflowhotThe current of the component generates heat, which deforms the bimetallic sheets with different expansion coefficients. When the deformation reaches a certain distance, it pushes the connecting rod to act, so that the control circuit is disconnected, so that the contactor is de-energized and the main circuit is disconnected.
