Patent ID: 7955102

Claim:
An electrical circuit quick connection and disconnection system with automatic short circuit of current transformer (CT) secondaries comprising a multipole plug ( 6 ) and receptacle ( 11 ) system for connecting a load ( 14 ) to a current transformer secondary circuit ( 3 B) with automatic short circuit capacity between poles ( 7 , 12 ) upon initiating a disconnection between the plug ( 6 ) and receptacle ( 11 ), without incurring any temporary opening of the circuit ( 3 B), further comprising a pair of male ( 7 ) or female ( 12 ) poles to which the CT ( 3 ) secondary ( 3 B) is connected being electrically connected to a series of fixed contacts ( 10 ) that can be short circuited by a series of moveable contacts ( 9 ) with the aid of one or more springs ( 8 ), in order to short circuit the CT secondary ( 3 B), and further comprising a locking system ( 15 ) that selectively restrains the moveable contacts separated from the fixed contacts, even if the plug and receptacle are not connected.
