摘要： A method an apparatus is disclosed for preventing contact welding during fault conditions. This fault current tolerable contactor includes two magnetic components, one in operable association with the movable contacts, and the other fixable attached above the movable contacts such that when a fault condition occurs, a high magnetic force is created to draw the two magnetic components together thereby opening the contacts. The magnetic force keeps the contacts open at least until current zero, and preferably a defined time thereafter to provide enough time for the contacts to cool and prevent welding upon the closure of the contacts.

摘要： An electric motor control apparatus includes an electrical current control apparatus which is operable to limit current to an electric motor. When the electric motor is a three-phase motor, three current limiting switch assemblies are provided in the electric current control apparatus. A single stack of laminations concentrates magnetic fields emanating from conductors in all three current limiting switch assemblies. Each of the current limiting switch assemblies includes two movable contacts which are mounted on contact arms. The contact arms are movable in slots in the stack of laminations. A first series of splitter plates is disposed in an array along a path of movement of the contact on the first movable contact arm and a second series of splitter plates is disposed along a path of movement of the contact on the second contact arm for each of the current limiting switch assemblies. A short circuit splitter plate conducts electrical current between the two series of splitter plates. A bypass splitter plate is connected in a bypass circuit which conducts excessive current around a motor starter to protect the motor starter.

摘要： A molded plastic current limiting circuit breaker having for each pole, a stationary and movable contact separable upon occurrence of a current higher than a predetermined level. The stationary and movable contacts are positioned inside an over-molded magnet opening to greatly increase the magnetic repulsion force between them and rapidly accelerate their separation by concentrating the magnetic fields generated upon an occurrence of a high level short circuit. The over-molded magnet is composed of a plurality of steel plates grouped together and being over molded with a thermoplastic material. The thermoplastic material has grooves integrally formed therein for retaining insulator inserts that protect the thermoplastic material during separation of the stationary and movable contacts.

摘要： A circuit interrupter includes an arc extinction assembly for magnetically driving or blowing out an arc formed between a stationary contact and a movable contact. The assembly comprises a pair of coaxial windings which are disposed in proximity to the contacts so that the internal lines of magnetic force generated by and passing inside of the windings can act directly on the arc for magnetically driving the arc in one direction. A magnetic flux diverting yoke is provided in association with the windings to diverse therethrough the external lines of magnetic force generated by and passing outside of the windings such that the arc and a portion of the movable contact arm carrying the same will not be under the influence of the external lines of magnetic force even when the contact separation proceeds to a stage where the arc is extended past the region which is totally under the influence of the internal lines of magnetic force. Otherwise, the external lines of magnetic force would pass through the arc and the portion of the movable contact arm in the opposite direction to the internal lines of magnetic force, causing the adverse magnetic effect of retarding the arc extinction and contact separation.

摘要： A contact structure (40, 44; 62, 63) is arranged to provide oppositely directed parallel current paths within a closed loop magnetic flux amplifier (46) to be directly separable under high overload current conditions, the flux amplifier (46) functioning to arrest the movable contact (62, 63) momentum. Manufacturing economies are realized by subassembling the stationary contact structure (40, 42, 44) and flux amplifier (46) and subsequently trapping one end (42a) of that assembly within the base (4a) and securing the other end with a single screw (68). The movable contact arm (62) comprises a plurality of blanked laminations assembled to provide improved contact (63) mounting and bearing (62d) surfaces. The molded case sidewalls are strengthened in the contact separation area by offsetting the parting line (PL) between cover (6) and base (4) closer to the bottom of base (4) and overlapping the thinner base sidewalls with thicker cover sidewalls at the offset (4e, 6e).

摘要： A circuit breaker having means for quickly opening a pair of contacts, a U-shaped flux board which surrounds the conductors that have contacts attached to the end portions thereof, so that the electromagnetic repulsive force produced by the electric current that flows through the opposing conductors in opposite directions relative to each other, will be added to the operation of the contact-opening means. The circuit breaker of the invention is further equipped with arc shielding members surrounding the contacts, so that the arc established across the contacts will not stretch to the conductors in the vicinities of the contacts, and so that the arcing voltage is greatly increased.

摘要： A rapid arc extinguishing assembly includes an arc chute comprising a large number of essentially parallel deionizing plates each in form of thin magnetically permeable, electrically conductive plates bent in U-shape, with the curve of the U facing the circuit breaker contacts and the arms thereof insulated from each other by a thin insulation sheet. To promote arc extinction by the arc chute and accelerated breaker contact separation, the breaker contacts are flanked by a magnetic assembly comprising opposed columns of parallel, spaced ferromagnetic plates embedded in an insulating material. The columns may be magnetically coupled by a yoke to create a closed slot in which the breaker movable contact travels.

摘要： A circuit breaker includes a slotted magnetic device having a plurality of spaced slotted conductive plates and a moving contact arm positioned within the slot when the circuit breaker is in a closed circuit position so that current flowing through the contact arm has a component in a vertical direction with respect to the slot. An overcurrent condition through the circuit breaker causes magnetic flux to be generated within the slotted magnetic device which develops a force to drive the moving contact arm from the front to the rear of the slot in a direction generally parallel to the bottom of the slot, thereby actuating the circuit breaker from a closed circuit position to an open circuit position. The circuit breaker also includes an arc-extinguishing device including a plurality of apertured conductive plates. The moving contact arm includes a probe member extending into the apertures of the plates when the circuit breaker is in a closed circuit position.
