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.
