Abstract

The invention discloses a miniature circuit breaker for side face plug-in installation. The circuit breaker consists of two miniature single-pole circuit breakers and a connection base, wherein the two miniature single-pole circuit breakers are connected in parallel with each other in a splicing mode; a groove is formed in the front side face of the connection base; the two miniature single-pole circuit breakers are inserted into the groove; conductive lug plates are arranged in the upper side faces and the lower side faces of the miniature single-pole circuit breakers respectively; connection ports are formed in the upper side face and the lower side face of the connection base respectively; wire frames and wiring boards are arranged in the connection ports respectively; and the wire frames are contacted with the conductive lug plates. When an applied circuit fails and the miniature circuit breaker needs replacing, the miniature single-pole circuit breakers are directly pulled out of the connection base without switching off a power circuit, repaired or replaced and reinserted into the connection base. After the miniature circuit breaker is separated from the connection base, a malfunction preventing mechanism is used for ensuring that switch-on is unavailable and a contact cannot be switched on when the circuit breaker is not fully inserted into the connection base, so that power operation is avoided.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to a circuit breaker, in particular to a plug-in miniature circuit breaker. 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 supply.
