Abstract
A circuit interrupter characterized by a multipole circuit breaker having line and load terminals and conductor means extending between the terminals for each pair of pole terminals, separate pairs of contacts serially connected in the conductor means, receiver means for sensing a control signal from an external source and sending a corresponding power signal to an operator means to effect opening of one of the pair of contacts.
Claims9
A circuit interrupter comprising a circuit breaker having a load terminal, a line terminal, conductor means extending between said terminals and including a first pair of contacts operable to open and close an electric circuit between the terminals, a second pair of contacts serially connected with the first pair of contacts in the conductor means, operator means for opening the second pair of contacts, said operator means including a two parallel connected coil solenoid, wherein both of said coils are energized to open said second pair of contacts, but only one of said coils is utilized to maintain said second pair of contacts in an opened state, receiver means for sensing a control signal from an external source and sending a corresponding power signal to the operator means to effect opening of the second pair of contacts.
A circuit interrupter comprising a multipole circuit breaker having line and load pole terminals and conductor means extending between the terminals of each pair of pole terminals, first and second pairs of contacts serially connected in the conductor means, operator means for simultaneously opening the second pairs of contacts, said operator means including a two parallel connected coil solenoid, wherein both of said coils are energized to open said second pair of contacts, but only one of said coils is utilized to maintain said second pair of contacts in an opened state, and receiver means for sensing a control signal from an external source and sending a corresponding power signal to the operator means to effect opening of the second pair of contacts.
