The invention provides a low-voltage universal vacuum circuit breaker, and relates to the technical field of low-voltage switches, comprising an insulating shell as well as an operation mechanism and an intelligent controller which are arranged outside the insulating shell. The vacuum circuit breaker is characterized in that: a vacuum arc extinguish chamber, a conductive loop and a transmission mechanism are arranged inside the insulating shell; the vacuum arc extinguish chamber is connected with a push rod and the transmission mechanism, and the push rod is driven to move up and down by the transmission mechanism to switch the switching state of the vacuum circuit breaker; the upper end of the vacuum arc extinguish chamber is connected with an upper bus by a soft connection mode, and the lower end of the vacuum arc extinguish chamber is provided with a conductive board, and is connected with a lower bus through a conductive board; and the conductive loop is formed among the upper bus, ...
