ABSTRACT:
In breaker devices an early short-circuit recognition is required and also a tripping of the contacts. The recognition of a short-circuit occurs so early that with consideration of the response time of the measuring probes and the unlocking mechanism by a suitable analysis algorithm the release of the movable contact occurs before or at least at the time that the current-breaking forces correspond to the contact force. The contact force is hence compensated for and a rapid opening of the contacts can be achieved.
