摘要： The present invention discloses an adjustable electromagnetic release. A magnetic yoke is fixed on a bracket. A conductor passes through the bracket and the magnetic yoke and is mounted on the bracket. A shaft is mounted on the top of the bracket and is above the conductor. A push rod is mounted on the shaft and rotates with the shaft about the bracket. An armature is fixed on the push rod, the armature and the magnetic yoke are spaced apart. Adjusting mechanisms are mounted on the shaft. The adjusting mechanisms are mounted between the push rod and the bracket and on both sides of the push rod. A torsion spring is surrounded on the shaft and is within the adjusting mechanism. The adjusting mechanism contacts with the push rod. An adjusting rod is provided with a plurality of adjusting surfaces which contact with the adjusting mechanism. The adjusting rod is able to move along the longitudinal direction. The spring force of the torsion spring enables the push rod rotates towards a direction which makes the armature and the magnetic yoke separate. When large current passes through the conductor, the armature and the magnetic yoke attract each other under the electromagnetic force. When the electromagnetic force is larger than the spring force, the push rod rotates towards a direction which makes the armature and the magnetic yoke close. The push rod strikes the release mechanism to release and cut off the circuit. The electromagnetic force disappears, the push rod resets under the spring force of the torsion spring.

摘要： A circuit breaker includes a trip mechanism having reduced trip movement and an integrated signal flag. The trip mechanism includes a spring-biased trip lever and a latching member for keeping the trip lever in an on or latched position. Upon occurrence of an abnormal current condition, the latching member is moved away from the trip lever to trip the trip mechanism. The latching member also has a catch mechanism designed to catch the trip lever after it is released, thereby halting further progress of both the trip lever and the latching member. As a result, less space is needed within the circuit breaker for trip movement compared to existing solutions. Moreover, the location of the catch mechanism on the latching member is selected such that the halting of the latching member places the integrated signal flag in an optimal viewing position within a viewing window.
摘要翻译：断路器包括具有减小的行程移动的跳闸机构和集成的信号标志。跳闸机构包括弹簧偏置的跳闸杆和用于将跳闸杆保持在接通或锁定位置的闩锁构件。当发生异常电流状况时，锁定构件移动离开脱扣杆以使脱扣机构跳闸。闩锁构件还具有止动机构，其设计成在脱扣杆被释放之后捕获脱扣杆，从而停止脱扣杆和闩锁构件的进一步进展。因此，与现有解决方案相比，用于跳闸运动的断路器中需要更少的空间。此外，卡扣构件上的卡扣机构的位置被选择为使得闩锁构件的停止将集成信号标志放置在观察窗内的最佳观察位置。

摘要： A divided armature for the trip mechanism of a circuit breaker especially useful for low trip current breakers allows for two independent adjustments: first of the magnetic air gap between the yoke and the armature and second of the clearance between the trip bar and the back plate of the armature. The divided armature allows the force of a return spring of the trip mechanism to be unchanged while adjusting the magnetic air gap to set the trip current point.
