Abstract
An exemplary working cylinder for a drive of an electric circuit breaker includes a base that includes a cylinder head and a cylinder body that are connected to one another. Additional components are fastened to the cylinder head as a core piece of the drive, and a thrust ring is guided on an outer surface of the cylinder body. The thrust ring compresses mechanical springs in the mechanical resilient energy storage device by way of a storage piston in a storage module.
