PURPOSE:To simply restart a motor by providing an overcurrent protecting element in a controller to prevent a defect due to an overcurrent and to set the element to resettable state. CONSTITUTION:A circuit protector 8 flows an overcurrent also to a bimetal inserted in series with a triac TR if the overcurrent flows to the triac TR, the bimetal is bent by the Joule heat, and a circuit breaker switch SW2 is opened. When the switch SW2 is opened, a pushbutton 7 is projected. Here, when desired to be returned to the normal state, the pushbutton 7 may be pressed. |
