An arcuate reset surface of the cradles independently engages a corresponding end of the cross member when the operating mechanism is moved toward the first position thereof. The cross member engages a linear latch surface of the cradles for latching the operating mechanism in the first position thereof.

摘要： A molded case circuit breaker incorporates vacuum switches operated by a toggle mechanism. Pole arms tied together by a cross bar are rotated simultaneously by the toggle mechanism. A drive link translates the rotational movement of each pole arm into linear movement of a driven member along the axis of the movable electrode of the associated vacuum switch. A coupling bracket has a base section secured to the movable electrode, longitudinal sections straddling the movable electrode axis and terminal sections extending inward toward the plane of rotation of the pole arm from the ends of the longitudinal sections. Coupling members extend from the driven member through slots in the terminal sections of the coupling bracket. Springs couple the free ends of the coupling members to the coupling bracket to open and close the vacuum switch with operation of the toggle mechanism.

摘要： A circuit breaker includes separable contacts for movement between a closed position and an open position to switch electrical current. An operating mechanism moves the separable contacts between the closed and open positions. A sensor senses the electrical current and outputs a sensed current signal corresponding to the electrical current. A shunt shunts a portion of the electrical current. A trip mechanism employs the sensed current signal to produce a trip signal. A trip actuator trips the operating mechanism to move the separable contacts to the open position. The trip actuator includes a trip solenoid having a coil energized by the trip signal and also includes one or more loops energized by the shunted portion of the electrical current.

摘要： A molded case circuit breaker is taught with a housing base and a primary cover disposed on the housing base. The primary cover has a recess therein for an auxiliary module which is disposed in the recess. A secondary cover is disposed on the primary cover for covering the recess when the auxiliary module is disposed therein. In order to secure the auxiliary module underneath the secondary cover in the recess of the primary cover, the module has deposed thereon a locking protrusion which is complimentary with a locking opening in the primary cover. The locking protrusion is flexible and has a longitudinal central bulge so that as the protrusion is pressed inwardly into the opening, the bulge causes the flexible protrusion to reduce diameter due to the presents of longitudinal slots therein until the bulge has passed the opening in which case it springs outwardly toward its normal position thus securing the protrusion in the base. A flexible pull tab is provided for displacement under the auxiliary or secondary cover so that when the auxiliary or secondary cover is removed the pull tab may be tugged upon to remove the module from the primary cover by providing the reverse operation to the insertion operation previously described.

摘要： A circuit interrupter handle mechanism is disposed on the face of a molded case circuit breaker. The handle mechanism has a rotary handle, which may be rotated through approximately 90° of rotation from a disposition of circuit interrupter conduction to a disposition of circuit interrupter non-conduction. The handle is not centered over the linear handle of the circuit interrupter per say, but rather is disposed in the upper left hand corner, so that a larger lever arm can be utilized. Furthermore, the larger lever has a handle opening into which the hasp of a lock may be placed to lock the circuit breaker in the open state for servicing and the like. Because of the length of the handle more hasps can be disposed therein than if the handle was disposed exactly in the center of the circuit breaker case. Lastly, the disposition of the circuit breaker rotary handle provides an indication of the conduction status of the molded case circuit breaker. If the handle is in a generally horizontal position, i.e., straight across the front of the circuit interrupter, that is an indication that the contacts of the circuit interrupter are open and that current therefore is blocked. If on the other hand the handle is 90° displaced, in a rotational manner, to be parallel with the long longitudinal axis of the circuit interrupter, then an indication is given that the circuit interrupter contacts are closed and current is being conducted.

摘要： Molded case electric power switches such as circuit breakers, disconnects and transfer switches have an energy storage spring which rotates a cam assembly to close and initiate opening of the switch contacts. The cam assembly includes a drive cam with a cam lobe which engages a drive cam follower on the moving contact assembly. Due to space limitations, the cam assembly is positioned so that the drive cam follower initially moves toward the cam assembly during closing. To accommodate for this, the cam lobe has a generally radial leading edge to prevent binding of the drive cam follower. A single latch mechanism latches the cam assembly in a spring charged position and in a closed position. A Y-shaped latch member has one leg which is engaged by a latch, a second leg which engages stops on the drive cam at the charged position and the closed position, and a third leg which sequentially engages the stops to reset the latch mechanism. The cam assembly, a charging mechanism including a rachet wheel and handle, the latch mechanism and the energy storage spring are all mounted between and supported by a pair of side plates. In a multi-pole switch, the drive cam engages the moving contact assembly of one pole which is coupled to the moving contact assemblies of the other poles by a cross-bar.
摘要翻译：模制电力开关如断路器，断路器和转换开关具有能量储存弹簧，其使凸轮组件旋转以闭合并启动开关触点的打开。凸轮组件包括具有凸轮凸角的驱动凸轮，凸轮凸角与可动触头组件上的驱动凸轮从动件接合。由于空间限制，凸轮组件被定位成使得驱动凸轮从动件在关闭期间最初朝向凸轮组件移动。为了适应这一点，凸轮凸角具有大致径向的前缘以防止驱动凸轮从动件的结合。单个闩锁机构将凸轮组件锁定在弹簧加载位置并处于关闭位置。 Y形闩锁构件具有由闩锁接合的一个腿部，在充电位置和关闭位置处接合在驱动凸轮上的止动件的第二腿部，以及顺序地接合止动件以重置闩锁机构的第三腿部。凸轮组件，包括旋转轮和手柄的充电机构，闩锁机构和储能弹簧都安装在一对侧板之间并由一对侧板支撑。在多极开关中，驱动凸轮接合一极的可移动接触组件，其通过横杆联接到另一个极的移动接触组件。
