    Abstract: An adjustable magnetic trip device for a molded case circuit breaker is provided where the trip device includes a plunger and a stationary core as well as a plunger support structure with a movable plunger carriage. The position of the plunger assembly and carriage relative to the stationary core is determined by a cam assembly having a body with a plurality of sections, each section having a different radius. The plunger carriage is responsive to rotation of said cam assembly and may be adjusted by rotating the cam. The over-current condition for the trip device is a function of the distance between the plunger assembly and the stationary core. Accordingly, the over-current condition may be changed by rotating the cam. As each section of the cam has a constant radius, the over-current condition remains the same no matter where the carriage contacts a certain section of the cam.

    Abstract translation: 提供了一种用于模制外壳断路器的可调磁脱扣装置，其中跳闸装置包括柱塞和固定芯以及具有可移动柱塞滑架的柱塞支撑结构。 柱塞组件和托架相对于固定芯的位置由具有多个部分的主体的凸轮组件确定，每个部分具有不同的半径。 柱塞滑架响应于所述凸轮组件的旋转，并且可以通过旋转凸轮来调节。 跳闸装置的过电流状态是柱塞组件和固定芯之间的距离的函数。 因此，可以通过旋转凸轮来改变过电流状态。 由于凸轮的每个部分具有恒定的半径，所以无论载架与凸轮的某一部分接触的情况，过电流状态都保持不变。

    Abstract: An accelerating mechanism in an overcurrent relay for accelerating the speed of moving operation of a resetting bar or the speed of motion in a normally closed contact caused by the resetting bar. In the application of the relay to any resetting mechanism, which effects resetting with a movement of the resetting bar, the relay can eliminate a very hazardous abnormal operation that a resetting operation is stored in a toggle mechanism, thus improving the safety of the resetting mechanism.

    Abstract: A reset rod (43) of a thermal overload relay is configured to be switchable between a manual reset position in which a reversal mechanism (21) is manually returned to an initial state prior to reversal by performing a pushing-in operation, and an automatic reset position in which a pushed-in state is held by a pushing and rotating operation from this manual reset position, and the reversal mechanism (21) is automatically returned to the initial position. In addition, axial runout restriction portions (17b, 17d, 51, 46 and 47), which restrict axial runout of the reset rod (43) when the reset rod (43) is held in the automatic reset position, are provided.

    Abstract: A thermal overload relay includes a main bimetal for detection of an overload current, a shifter associated with the main bimetal, a release lever working according to a displacement of the shifter, a contact reversing mechanism for changing-over contacts by reversing action caused by rotation of the release lever, and a manipulation structure for manipulating the release lever and the contact reversing mechanism. The manipulation structure includes a reset bar for returning the contact reversing mechanism to an initial state. The reset bar is arranged to change-over between a manual reset state in which the reset bar can be pushed-in and an automatic reset state in which the reset bar is pushed-in and turned from the manual reset state and held in that state.

    Abstract: Apparatus for adjusting the calibration of a thermal trip unit which is to be used in conjunction with an electrical circuit breaker. A rotatable knob is provided which adjusts the trip unit to between one hundred percent of the rating of the circuit breaker and some value which is less than one hundred percent. An adjustable stop screw is provided to engage the rotatable knob when the knob is rotated to adjust the calibration of the trip unit to the desired value which is less than one hundred percent of the rating of the breaker. The adjustable stop screw thereby limits travel of the adjustable knob between only one hundred percent of the rating of the circuit breaker and the desired value which is less than one hundred percent.
