Small circuit breaker for plug-in installation

Abstract

The invention relates to a small circuit breaker for plug-in installation, which consists of two small single-pole circuit breakers and a wiring base, wherein the two small single-pole circuit breakers are in assembly connection in parallel through rivets; the upper part and the lower part of the back lateral surface of any small single-pole circuit breaker are provided with a binding post respectively; the upper part and the lower part of the wiring base are provided with two wiring sleeves at intervals respectively; the binding posts are in nested connection with one wiring sleeve respectively; the wiring base is arranged on a clamping rail of a distribution box; and an upper wiring board and a lower wiring board of the wiring base are connected with a power-supply side connecting wire and a load side connecting wire respectively. When an application circuit generate faults and the small circuit breaker needs to be replaced, the two small parallel single-pole circuit breakers are pulled out of the wiring base directly without cutting off power supply, and after being maintained or replaced, the small single-pole circuit breakers are plugged in the wiring base again; and after the small single-pole circuit breakers leave away the wiring base, handles of the two small single-pole circuit breakers are locked by utilizing a lever mechanism so as to prevent the false operation ofthe handles and power operation.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to a circuit breaker, in particular to a small circuit breaker for plug-in installation. Background technique: [0002] In the prior art, all miniature circuit breakers are mounted on rails. The circuit breaker is fixed on the standard rail, and the upper and lower parts of the circuit breaker have wiring frames, which are connected to the power supply side and the load side by wire connection screws. When the product breaks down and needs to be repaired or replaced, it is necessary to disconnect the power supply, then remove the wires, remove the product from the rail, install a new product, then connect the wires, and then turn on the power supply. During this installation process, the line power supply is discontinuous, so it is not suitable for installation, removal and maintenance in industries such as data centers and communication power supplies that require continuity of power suppl...
