Abstract

A load circuit breaker comprises a switch body and a wire outlet module detachably connected with the switch body, the switch body comprises a body shell, an operating mechanism and at least one phase circuit, the operating mechanism and the phase circuit are arranged in the body shell, and each phase circuit comprises a wire inlet busbar, a wire outlet busbar, a contact system and a fuse, and the contact system and the fuse are connected in series. The wire outlet module is provided with a wiring terminal connected with a wire outlet busbar, one end, far away from the operating mechanism, of the body shell is provided with a first wire outlet hole, and one side of the body shell is provided with a second wire outlet hole; the wire outlet module is installed at one end, far away from the operating mechanism, of the switch body, the wire outlet busbar extends into the wire outlet module from the first wire outlet hole to be connected with the wiring terminal, or the wire outlet module is installed on the side face of the switch body and is arranged side by side with the switch body, and the wire outlet busbar extends into the wire outlet module from the second wire outlet hole to be connected with the wiring terminal. Different wiring schemes are provided for users to adapt to different systems of the users.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a load breaking switch. Background technique [0002] Load-break switch, with energy storage isolating switch and pluggable fuse group, is an important switching appliance in the power distribution system. Open circuit, fuse bank provides current protection. [0003] When the load-break switch is installed, due to the limitation of installation space, there are different wiring directions and wiring requirements with different types of wires. Existing load-break switches usually can only be adapted to one assembly method. When different wiring requirements need to be adapted, different load-break switches need to be used, and the cost is high. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the defects of the prior art and provide a load break switch. [0005] To achieve the above object, the present invention has adopted...
