Abstract
A plug-in type miniature circuit breaker consists of two miniature single-pole circuit breakers and a connection base. The two miniature single-pole circuit breakers are assembled and connected in parallel through a rivet; connection terminals are respectively arranged at the upper part and the lower part on the rear lateral surface of either miniature single-pole circuit breaker; two connection sleeves are respectively arranged at the upper part and the lower part of the connection base at intervals; each connection terminal is connected with each connection sleeve in a nesting manner; the connection base is mounted on the card track of a power distribution cabinet; and an upper connection board and a lower connection board of the connection base are respectively connected with a power supply-side connection and a load-side connection. When the miniature circuit breaker is required to be replaced due to the failure of an application circuit, the two parallel miniature single-pole circuit breakers are directly pulled out from the connection base without power failure and then plugged into the connection base after being maintained and replaced. In addition, the handles of the two miniature single-pole circuit breakers are locked by utilizing a lever mechanism when the miniature single-pole circuit breakers keep away from the connection base, so that the handle malfunction is prevented and the live operation is avoided.
