ABSTRACT:
A multi-pole high-power circuit-interrupter is provided having a single common operating mechanism therefor, and having independent pole tripping operation by associating with at least one of a plurality of the pole-units its independent ball latching means, which may be very quickly mechanically released upon a tripping operation associated with the respective one pole-unit to which said ball latching device is connected.
Another important feature of the invention is the provision of a plurality of load-release latching balls, which may be quickly released from their latched position by a pneumatic releasing device, which is energized in response to electrical overload conditions existing in the respective pole-unit to provide thereby a tripping operation for the particular pole-unit, to which the ball-latching releaseable device is mechanically connected.
Still another feature of the present invention is the provision of a spring-return catch-member in a ball-latch releasing device, which holds the load-release balls in their latched position, and provides a desirable quick relatching operation at the end of the closing operation of the circuit-interrupter.
