The invention particularly discloses an improved control circuit for a power load control terminal. The improved control circuit comprises a load control terminal control circuit, an alternating current contactor control circuit, an intermediate relay and a normally-closed reset switch, wherein a main contact point and a normally-opened auxiliary contact of the intermediate relay are connected in parallel and then are connected to the load control terminal control circuit; the normally-closed reset switch is connected with the main contact of the intermediate relay in series; and the normally-closed auxiliary contact of the intermediate relay is connected to the alternating current contactor control circuit in series. The improved control circuit disclosed by the invention has the benefits that the intermediate relay accesses to the control circuit of the load control terminal and the alternating current contactor in a serially-connected way on the basis that original equipment of power users is not replaced, and thus the control effect is achieved. The improved circuit is simple in wiring construction process and is convenient for wiring; and the time is controlled within 45 minutes, so that the construction time is greatly shortened.
