ABSTRACT:
Tripping devices, more particularly for circuit-breakers, in which a single model tripping device can be transformed by a simple operation, not requiring any dismantling, to obtain either a shunt or undervoltage type of operation. This result can be obtained by changing the relative position of a catch part of the striker, for example by rotation through 180 degrees in relation to a locking part.
