Abstract
A self-recovering current-limiting device having liquid metal includes solid metal electrodes for connecting to an external electric circuit to be protected. A plurality of compression spaces which are partially filled with liquid metal are arranged one behind the other between the electrodes and are formed by pressure-resistant insulating bodies and by insulating partitioning walls having connecting channels. An enclosing insulating shaped housing is provided having a trough-like bottom part and a cover that tightly closes the bottom part via a non-positive and/or positive connecting device. The partitioning walls and the bottom part are interconnected as one piece. The connecting channels are configured as longitudinal holes which are open at the top. The electrodes are mounted in the bottom part. The nominal current range of the device may be easily adjusted.
