Abstract
A self-regenerating liquid metal current limiter including solid metal electrodes for connection to an electric circuit to be protected and several compression chambers which are partially filled with liquid metal. The compression chambers are located one behind the other between the electrodes and are formed by pressure-resistant insulating bodies and by partition walls with connecting channels that are supported by the insulating bodies. The partition walls are provided with a plurality of connecting channels that are not arranged in a generally concent arrangement with respect to a substantially horizontal longitudinal axis of the current limiter, the axis extending in a direction perpendicular to the partition walls. The current limiter provides for various positions of use corresponding to a position of rotation of the current limiter about its longitudinal axis.
