ABSTRACT:
A multi-pole high-power circuit-interrupter is provided having a common operating mechanism, and having independent pole operation by associating with each of the several pole-units its own independent collapsible latching means, which may be very quickly released upon a tripping operation associated with the respective pole-unit to which said latch is individually connected.
Another important feature of the invention, is an overlapping toggle arrangement, in which the toggle is overlapped in the closed-circuit position of the circuit-interrupter, and may be very quickly released to an extended unlatched position, for example, by an electromagnetically-operated tripping device, such as a repulsion coil, for example.
