Abstract

A modular cost-effective drive system for electrical switching devices of medium-voltage installations is specified. The drive system, by the addition or omission of individual components, can be used both as a three-position disconnector with a snap-action or storage drive function and as a two-position circuit breaker which can also be expanded by a brief interruption function.
