The invention discloses an electric energy meter external reclosing function circuit breaker. The electric energy meter external reclosing function circuit breaker includes a circuit breaker body, a display screen and a control handle, wherein the circuit breaker body has a rectangular structure, the display screen is embedded on a front surface, the control handle is arranged at a lower part of the front surface of the circuit breaker body, and the circuit breaker body internally includes a breaking mechanism, an embracing buffer mechanism and a metal vapor replenishing mechanism. The electric energy meter external reclosing function circuit breaker is advantaged in that through the embracing buffer mechanism, when the circuit breaker is opened, contacts are held in an embracing airbag mode for buffering, a problem of burning damage to the circuit breaker because of reignition caused by severe vibration due to relatively large rebounding force is avoided, the circuit breaker is effectively protected, moreover, through the metal vapor replenishing mechanism in combination with opening arc-extinguishing zero-crossing, metal vapor is generated to supplement a distance pulled apart bythe contacts, and occurrence of overvoltage caused by interception is prevented.
