摘要： A short-circuit protection action current adjusting method and a device thereof for a multi-pole electromagnetic release. An electromagnetic system includes an auxiliary static iron core, a second static iron core, a coil, a reset spring and a dynamic iron core; at an initial position, a first gap is formed between the auxiliary static iron core and the dynamic iron core, a second gap is formed between the dynamic iron core and the second static iron core, and the thickness of the second gap changes in the same direction along with the size variation of a release threshold; the elastic force of the reset spring changes oppositely along with the size variation of the release threshold; when a release current value is adjusted from large to small, the coil energy reduces in a quadratic relationship mode along with flowing currents and meanwhile the electromagnetic attraction between the dynamic iron core and the second static iron core is increased in a quadratic relationship mode, which is in inverse proportion to reduction of the thickness of the second gap. According to the short-circuit protection action current adjusting method and device thereof for the multi-pole electromagnetic release, adjustment of the release current value and electromagnetic attraction required by actions of the dynamic iron core are in a linear fixed corresponding relationship due to automatically achieved balance between two quadratic functions, and adjustment of the release threshold through the user is convenient, reliable and stable.

摘要： A solenoid assembly for a circuit breaker having a clapper with an increased mass is provided. The mass, preferably at least one non-ferrous slug, increases the mass of the clapper so that the solenoid response time is slowed. That is, the added mass creates an inertial delay that slows the solenoid clapper as the clapper moves between the first position and the second position. Preferably, the delay is between 48 ms and 60 ms, and more preferably 50 ms. The clapper having a non-ferrous slug may also be incorporated into existing circuit breakers by, for example, coupling the non-ferrous slug to the preexisting clapper, or replacing the clapper with a clapper assembly having at least one non-ferrous slug thereon.

摘要： An adjustable magnetic trip unit for a circuit breaker includes a torsion spring which applies a bias force to the plunger of a trip solenoid. The torsion spring is mounted on a driven bevel gear and wound by an adjustment knob coupled to a driving bevel gear to adjust the current at which the solenoid is activated. An indexer having peripheral flats which engage a seat in the circuit breaker housing provides a plurality of discrete positions of the adjustment knob. Depressing the adjustment knob against a second spring unseats the indexer for rotation of the adjustment knob between settings. In addition, a slide with an inclined surface bearing against the plunger and coupled to the driven bevel gear, provides simultaneous adjustment of plunger gap with adjustment of the torsion spring force to increase the range of adjustment.
