PURPOSE: A vacuum circuit breaker having a mechanism for absorbing impacts on a mold housing due to an electromagnetic force applied by adjacent busbar type terminals are provided to prevent an insulating material mold housing from breaking down by rapidly moving the busbar type terminal when a fault is generated. CONSTITUTION: In a vacuum circuit breaker having a mechanism for absorbing impacts on a mold housing due to the electromagnetic force applied by adjacent busbar type terminals, a vacuum interrupter is proved in each phase of three phases. A plurality of burbar type terminals are electrically connected to the vacuum interrupter respectively. The insulating material mold housing(30) accepts the vacuum interrupter and busbar type terminal. At least one absorbing mechanism is installed between the insulating material mold housing and the busbar type terminal. The absorbing mechanism alleviates the impact applied to the insulating material mold housing.
