Abstract

The two switches are mounted side-by-side, and both have the same outlines. The leakage current switch operates through a transmission element the line protection switch trips. The leakage current switch trip consists of a locking mechanism (1-12) corresponding to that of the line switch. It is unlocked by an energy store (13, 16) which in turn in released by a relay excited by the leakage current. Transmission of the unlocking process is performed through a coupling (12) used in multiple pole line protection switches.
