Abstract

The present invention relates to a circuit breaker, comprising: - a vacuum interrupter (10); - a lever system (50); - a drive shaft (70); and - a coupler (80); wherein the vacuum interrupter comprises a fixed contact and a moveable contact; wherein a first end of the lever system is connected to the moveable contact; wherein a first part of the coupler is connected to the drive shaft, and wherein the first part of the coupler is at an on-axis location of the drive shaft; wherein a second part of the coupler is connected to a second end of the lever system, and wherein the second part of the coupler is at an off-axis location of the drive shaft; wherein a first rotation of the drive shaft in a first direction is configured to provide a first rotation to the second part of the coupler around the axis of the drive shaft in the first direction; and wherein the first rotation of the second part of the coupler around the axis of the drive shaft in the first direction is configured to activate the lever system to move the moveable contact towards, and come into contact with, the fixed contact.
