Abstract

Improvements in the construction of defective current-protector switches, with a transmission element, which has a magnetic core provided with primary windings for connection to a circuit to be controlled, and with an electric trigger acting on a switching ratchet for a switching installation, which is in dependence of the control of the transmission element, characterized in that a magnetic field probe is placed in the magnetic core of the transmission element as a control element for the electric trigger.
