摘要： A magnetic trigger mechanism with a yoke with armature opening. The armature is coaxially surrounded by a coil having an excitation coil, which is acted on by a force of a preloaded spring and which remains in a first end position due to magnetic holding force of a permanent magnet when there is no current flowing through the excitation coil. The permanent magnet is arranged at a first end of the armature and the second end position of the armature being achieved by a brief flow of current through the excitation coil together with the accompanying lowering of the magnetic holding force and the spring force. The first end of the armature is guided in the coil body, and the second end position, which faces the armature opening, is guided by a centering ring, the highly permeable centering ring rests against the yoke at the armature opening and can move.

摘要： An accessory includes a trip arm biased by a spring to pivot in a clockwise direction about a trip arm pivot. A latch is arranged to pivot about a latch pivot and has the trip arm acting on a latch surface on the latch to bias the latch in a counter clockwise direction about the latch pivot. An electromechanical device including a plunger acts on the latch pulling it clockwise about the latch pivot. When a signal is provided to the electromechanical device, the plunger is released allowing the trip arm to pivot clockwise about the trip arm pivot due to the spring and actuates the operating mechanism. To reset the trip arm and the latch, a reset lever is arranged to pivot about the latch pivot. The reset lever includes a tab portion configured for interfacing the operating mechanism, and a drive portion for interfacing the trip arm. This, when the operating mechanism is reset, a portion extending from an operating handle interfaces the tab portion to pivot the reset lever clockwise about the latch pivot. The drive portion interfaces the trip arm to drive the trip arm counterclockwise about the trip arm pivot.

摘要： A trip circuit for tripping a circuit breaker has a first coil having a relatively large number of turns and therefore a relatively slow reaction time and a second coil having a relatively small number of turns and therefore a relatively fast reaction time. The first coil is responsive to a relatively low current level through a circuit breaker for tripping the circuit breaker at the rated tripping current. The second coil is responsive to a higher current through the circuit breaker for tripping the circuit breaker with great rapidity in case the higher level is reached before the first coil has an opportunity to react.

摘要： A high-sensitivity electromagnetic relay comprises a magnetic circuit polarized by a permanent magnet, a flux distributor, an operating coil, and a moving core cooperating with the flux distributor by means of an air-gap. A return spring passes completely through the core being inserted between the flux distributor and the external end of a guide tube, which is shaped as a bottle-neck having a widened part housing the core, and a narrow part capable of sliding in an aperture.

摘要： A magnetic trip unit for a circuit breaker having an armature and a plunger; the armature completes a magnetic path through the poles of a permanent magnet; the armature and plunger are biased toward trip position but are held by the permanent magnet and may be restored to the position where the armature completes the path through the poles of the permanent magnet. A trip coil is provided surrounding the permanent magnet and armature. A casing of magnetic material surrounds the trip coil and extends below the armature; this casing also has top and bottom walls of magnetic material and an inner cup shaped sleeve bearing against the bottom wall and against one pole of the permanent magnet. Energization of the trip coil establishes an additional magnetic path through the armature and the one pole of the permanent magnet which opposes the magnetic force of the first mentioned magnetic path and permits the bias on the armature and plunger to move them to trip position.

摘要： A low energy mechanically driven and electromagnetically actuated ground fault trip indicator is taught. The ground fault trip indicator utilizes the magnetic flux of a permanent magnet in a first flux path to maintain a movable armature biased against a spring. An electromagnet is disposed to provide magnetic flux in opposition to the magnetic flux of the permanent magnet. The electromagnet is not energized for providing the opposing flux until a pulse is received from an appropriate ground fault trip detecting circuit. When the appropriate pulse of energy is applied to the electromagnet, a portion of the flux of the permanent magnet is cancelled allowing the spring to force the armature into a new position. In this position the flux of the permanent magnet is reestablished in a second flux path. When the indicator is in the latter position indication of the occurrence of a ground fault is given.

摘要： A molded case multi-pole circuit breaker is provided with a solid state trip unit constructed to automatically open the breaker responsive to predetermined fault current conditions by actuating a permanent magnet latch. The latch and main conductors of the circuit breaker are constructed and arranged so that at very high short circuit currents, even if the solid state circuitry malfunctions, flux generated directly by current flow in the main conductors will buck the permanent magnet flux sufficiently to actuate the magnetic latch directly.
