Patent ID: 7781689

Claim:
A retrofit handle assembly for a network protector enclosure, said enclosure having at least a tank with a plurality of generally planar sidewalls defining an enclosed space, at least one said sidewall having an opening therethrough and another sidewall being removable thereby providing access to said enclosed space, said tank further having a pair of elongated extendable rails structured to support a circuit breaker, said circuit breaker having a frame assembly, a housing, an operating mechanism, and a trip device, said operating mechanism having a shaft with an exposed end, said circuit breaker being movably disposed on said rails and being movable between an installed position, wherein said circuit breaker is within said tank, and a withdrawn position, wherein said circuit breaker is substantially outside said tank, and wherein, when said circuit breaker is in said installed position, said operating mechanism shaft exposed end is disposed adjacent to said sidewall opening; said retrofit handle assembly comprising: a circuit breaker assembly having an elongated torpedo fixed to said operating shaft exposed end, wherein rotation of said torpedo causes said operating mechanism to be actuated; a tank assembly having an external handle member and a torpedo bracket; said handle member being disposed outside of said tank and being operatively coupled to said torpedo bracket wherein rotation of said handle member causes said torpedo bracket to rotate; said torpedo bracket sized to snugly, but removably, engage said torpedo; said torpedo structured to be engaged by said torpedo bracket when said circuit breaker is in said installed position; and wherein said circuit breaker operating mechanism may be actuated by said handle member.
