摘要： An operating mechanism for an enclosure-mounted circuit breaker includes a slider for engaging the circuit breaker handle; a shaft-driven pivot for moving the slider between the handle on, off and reset positions; a holder for holding the slider in its reset position; a base plate for supporting the pivot and the slider; and a door-mounted rotary handle for rotating the shaft and operating the pivot. The rotary handle may engage the shaft in the on and off positions, and may be detached from the shaft in the reset position. The pivot may include a first pivot arm having a first cam surface for holding the slider in its reset position. A second cam surface on a second pivot arm may engage a first slider surface from off to on; a second slider surface from on to off, from off toward reset, and to resist reset to off; and an oblique slider surface when adjacent reset. The second cam surface may disengage the oblique surface at reset. Alternatively, the slider may include a notch and the base plate may include a latch for engaging the notch. The pivot may include a single pivot arm having a cam surface which engages a slider surface from off to on; an oblique slider surface from on to off, and from off to reset in order to engage the notch and the latch; and another oblique surface to disengage the notch and the latch from reset to off. The slider may include an oblique shoulder for moving the handle from on to off and from off to reset, for resisting the handle force from reset to off, and for using the handle force to engage the notch and the latch in the reset position in order to substantially decouple the handle force from the rotary handle.
摘要翻译： 用于机壳安装式断路器的操作机构包括用于接合断路器手柄的滑块; 轴驱动的枢轴，用于在手柄开，关和复位位置之间移动滑块; 用于将滑块保持在其复位位置的保持器; 用于支撑枢轴和滑块的基板; 以及用于旋转轴并操作枢轴的门安装的旋转手柄。 旋转手柄可以在打开和关闭位置处接合轴，并且可以在复位位置从轴脱离。 枢轴可以包括具有用于将滑块保持在其复位位置的第一凸轮表面的第一枢转臂。 第二枢转臂上的第二凸轮表面可接合第一滑块表面从脱开到开; 第二滑块表面从开到关，从关到复位，并且抵抗重置到关闭; 和相邻复位时的倾斜滑块表面。 第二凸轮表面可以在复位时使倾斜表面脱离。 或者，滑动器可以包括凹口，并且基板可以包括用于接合凹口的闩锁。 枢轴可以包括单个枢转臂，其具有凸轮表面，所述凸轮表面使滑动器表面从关闭到接合; 倾斜滑块表面从开到关，并从关闭到复位以便接合凹口和闩锁; 和另一个倾斜表面，以使凹口和闩锁脱离复位到关闭。 滑块可以包括用于将手柄从开到关并从关闭到复位的倾斜肩部，用于阻止手柄力从复位到关闭，并且为了使用手柄力使凹口和闩锁按顺序接合在复位位置 以使把手力基本上与旋转手柄分离。

摘要： The handle of an electrical switch reciprocally movable in a slot in the switch housing is locked in a desired position by a locking mechanism which includes a base plate secured to the housing adjacent one end of the handle slot. A hasp member is hinged to the base plate at a hinge end for rotation about a hinge axis transverse to the path of reciprocal movement of the handle. The hasp member is rotatable between a locking position in which it overlaps the front end of the slot so that the handle cannot be moved away from the second end of the slot. A staple extending transversely from the base plate protrudes through an opening in the hasp member and has an opening for receiving one or more padlocks for locking the hasp member in the blocking position. In a second embodiment, the hasp member has a second opening through which the handle protrudes for locking the handle at the front end of the slot. Notches in arcuate fingers forming the hinge connection for the hasp member are engaged by sliding the hasp member axially on the hinge connection to latch the hasp member clear of the handle which allows unrestricted movement of the handle even with the switch mounted vertically.

摘要： The handle operator for a circuit breaker mounted in an enclosure is locked in the OFF position when the enclosure is opened by a lock-out member which directly engages the operator member of the handle operator which contacts and moves the circuit breaker handle. The lock-out member is a metal plate having an engagement edge which is positioned transverse to an engagement edge of the metal plate forming the handle operator member. Preferably, the lock-out member plate has a slot in which the engagement edge of the operator plate is received. The operator plate is pivotally mounted for rotation in its own plane and the lock-out plate slides parallel to the operator plate and has a flange providing the engagement edge which engages the operator plate at a point where any attempt to rotate the operator plate to move the circuit breaker handle toward the ON position, jams the lock-out plate into tighter contact with the operator plate. Preferably, the flange of the lock-out plate is bent at an angle which places it perpendicular to the engagement edge of the operator plate when engaged.
