The invention discloses a low-voltage electricity charge control box, and relates to the field of electricity charge control devices. The low-voltage electricity charge control box comprises two AC contactors which are a small AC contactor and a large AC contactor. Disconnection or connection of the two AC contactors are controlled by using tripping turn normally-open and normally-closed contacts of a three-phase four-wire remote electricity charge control intelligent electric energy meter so as to realize power failure and power supply recovery of users, thereby realizing implementation of an electricity charge control function for the users. The coil current of the small AC contactor is low, the service life of a relay of the electric energy meter can be prolonged, and the efficiency of the relay of the electric energy meter is improved. Additional arrangement of the small AC contactor can prevent the relay inside the electric energy meter from being damaged by long-term opening and closing. The low-voltage electricity charge control box is reasonable in structure, convenient to control, long in service life and low in cost.
