Abstract
Abstract Controlled switching apparatus mountable in a conventional residential panelboard includes a conventional molded case circuit breaker module mounted in adjacent side-by-side relation with an operator module. The latter is remotely operated and includes a single remotely operated electrically energized unidirectional actuator which oscillates a rocker connected to the circuit breaker handle for selective movement thereof between its On and Off positions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
Controlled switching apparatus including a circuit breaker section and a remotely controllable operator section; said circuit breaker section including a set of cooperating contacts, trip-free spring powered operating means operatively connected to said contacts, said operating means including a manually movable operating member for selectively opening and closing said contacts, said operating member being oscillatable about a first fixed pivot as a center, fault responsive trip means operatively connected to said operating means for automatic activation thereof to open said contacts upon the occurence of predetermined fault conditions; said operator section including a rocker mounted on a second fixed pivot, a single remotely operated electrically energized unidirectional actuator operatively connected to said rocker to oscillate the latter about said second pivot as a center; said first and second pivots being axially aligned; and connecting means joining said operating member to said rocker for simultaneous operation whereby motion of said rocker controlled by actuation of said actuator is effective to move said operating member for both opening and closing said contacts.
Claim 2
Dependent Claim
170 words
Controlled switching apparatus including a circuit breaker section and a remotely controllable operator section; said circuit breaker section including a set of cooperating contacts, trip-free spring powered operating means operatively connected to said contacts, said operating means including a manually movable operating member for selectively opening and closing said contacts, said operating member being oscillatable about a first fixed pivot as a center, fault responsive trip means operatively connected to said operating means for automatic activation thereof to open said contacts upon the occurence of predetermined fault conditions; said operator section including a rocker mounted on a second fixed pivot, a single remotely operated electrically energized unidirectional actuator operatively connected to said rocker to oscillate the latter about said second pivot as a center; said first and second pivots being axially aligned; and connecting means joining said operating member to said rocker for simultaneous operation whereby motion of said rocker controlled by actuation of said actuator is effective to move said operating member for both opening and closing said contacts.
Claim 3
Dependent Claim
65 words
Controlled switching apparatus as set forth in claim 1 in which the operator section also includes positioning means interposed between said rocker and said actuator to move the latter to first and second positions when said rocker is in respective third and fourth positions; said operating member being in contact open and closed positions when the rocker is in said third and fourth positions, respectively.
Claim 4
Dependent Claim
106 words
Controlled switching apparatus as set forth in claim 2 in which the actuator moves between the first and second positions on a third fixed pivot; said actuator including a normally retracted plunger mounted for axial movement in a power stroke to drive said rocker upon actuation of said actuator; with said actuator in said first position axial movement of said plunger in said power stroke being directed on one side of a line extending through said second and third pivots and with said actuator in said second position axial movement of said plunger in said power stroke being directed on the other side of said line.
Claim 5
Dependent Claim
51 words
Controlled switching apparatus as set forth in claim 3 in which the positioning means includes a crank pivotally mounted on a fourth fixed pivot, a first link connecting said crank to said rocker and a second link connecting said crank to said actuator at a point remote from said third pivot.
Claim 6
Dependent Claim
18 words
Controlled switching apparatus as set forth in claim 4 in which the second link includes a spring means.
Claim 7
Dependent Claim
34 words
Controlled switching apparatus as set forth in claim 5 in which the spring means includes a resilient wire member having end portions movable away from one another with respect to their normal relative positions.
Claim 8
Dependent Claim
30 words
Controlled switching apparatus as set forth in claim 3 in which the plunger includes a free end portion which makes direct driving engagement with said rocker during said power stroke.
Claim 9
Dependent Claim
28 words
Controlled switching apparatus as set forth in claim 7 in which the free end portion of the plunger is disengaged from said rocker when said plunger is retracted.
Claim 10
Dependent Claim
31 words
Controlled switching apparatus as set forth in claim 1 in which the actuator includes a normally retracted plunger mounted for axial movement in a power stroke upon actuation of said actuator.
Claim 11
Dependent Claim
23 words
Controlled switching apparatus as set forth in claim 9 in which the actuator is comprised of a fluid-thermal device which is electrically energized.
