| A switch actuator mechanism, for example for use with a circuit breaker, includes a rocker which has first and second rocker members which are hinged together. The rocker members have flat front faces which are movable between a condition in which they lie flat in the same plane, and a second position in which the faces are inclined relative to one another, with one rocker member standing proud of the housing of the switch or circuit breaker. Fingers on one of the rocker members engage a link of the circuit breaker mechanism to open or close its contacts. A spring loaded latching mechanism locks the rocker members alternately in their first and second conditions with successive operations of the mechanism. | ||||||
| 110 | Return spring for a circuit interrupter operating mechanism | US09527479 | 2000-03-16 | US06459059B1 | 2002-10-01 | Randy Greenberg; Roger N. Castonguay; Dave Christensen; Hassan Girish |
| A return spring mechanism is arranged to operate with a circuit breaker operating mechanism during a trip condition. The circuit breaker operating mechanism is movable between a tripped position, a reset position, an off position and an on position. The return spring mechanism is attached to the exterior of the circuit breaker frame and includes a return spring with a fixed end attached to the frame. When the circuit breaker is tripped, the return spring mechanism operates to provide an additional force to the handle yoke. The additional force applied by the return spring is predetermined to position the handle yoke intermediate to the handle yoke positions when the circuit breaker is off and on. Thus, the movement of the handle yoke to the intermediate position provides clear indication that the circuit breaker is in the tripped condition. | ||||||
| 111 | Trip link latch and interpole link for a circuit breaker | US814975 | 1991-12-23 | US5214402A | 1993-05-25 | Gregory T. DiVincenzo; John C. Lucas; Keith A. Singer |
| Tripping of the poles of a multi-pole breaker requires less force from current sensing actuators, through use of a lost motion linkage including a trip link which unlatches the linkage holding one pole contact set closed before operating the inter-pole tripping elements. Preferably the breaker has a fast forcing arrangement for forcing a movable contact open under short-circuit conditions, faster than the normal contact opening spring can respond. The lost motion linkage is provided by a trip link which first releases a secondary latch to permit contact opening at normal speed, and then operates an inter-pole tripping element. Under short-circuit conditions the trip link engages the movable contact to force it open, between unlatching and engagement of the inter-pole tripping element. | ||||||
| 112 | Molded case circuit breaker operating handle guard | US608789 | 1990-11-05 | US5060107A | 1991-10-22 | Roger N. Castonguay |
| A molded case circuit breaker with a visual access slot next to the circuit breaker operating handle allows the conditions of the circuit breaker contacts to be visually ascertained. To prevent inadvertent displacement of the circuit breaker operating handle when the circuit breaker is connected within an electrical distribution circuit, a handle guard is positioned over the circuit breaker operating handle. The handle guard is arranged such that the circuit breaker operating handle is free to reciprocate between the ON, OFF and TRIPPED positions while the operating handle guard is in position. | ||||||
