Abstract
An improved circuit breaker with remote control capability includes an electromagnet energized by a remote control signal to open and close a power contact through a collapsible mechanical linkage. The breaker also includes a manual handle which is mechanically isolated from the mechanical linkage interposed between the electromagnet and the power contact but is connected to a control switch for opening and closing the same when it is manipulated between an ON-position and an OFF-position. The control switch is utilized to be connected in a control circuit for the electromagnet in a suitable electrical relation with an excitation coil of the electromagnet to provide a desired load managing control mode. A fault current responsive tripper is interlocked with the mechanical linkage so as to collapse the same for opening the power contact upon the occurrance of a predetermined fault current condition, whereby the circuit interruption due to the fault current condition can be effected by directly driving the mechanical linkage and without actuating the electromagnet.
