Abstract
A contactor apparatus is provided comprising automatic opening means and a local control member. This apparatus uses a transmission piece (40) associated with a sudden tripping mechanism (46) which is released by a bolt (29) held in position by means of a lever (24) which may be struck by a magnetizable part and adapted to maintain a power contact (13) open, this part assuming, after the appearance of a fault, visible positions so as to inform the user about the state of the apparatus. This apparatus is usable in installations where it is desired to protect the lines and the loads.
