摘要： A circuit breaker is disclosed for interrupting an electrical circuit when current limit values are exceeded. The circuit-breaker includes a current sensor for determining the electrical current flow and a control device. When current limit values are exceeded, the electrical circuit is interrupted. A first current limit value, when exceeded, results in an immediate interruption and a second current limit value, when exceeded, results in a time-delayed interruption, such that the second interruption time reduces as the current increases. Only one control element is included for setting a current limit value. The element defining the second current limit value is included for the time-delayed interruption of the electrical circuit. The other parameters are either set in a fixed manner and/or are related to the settable second current limit value.

摘要： A delay time generation apparatus for an air circuit breaker according to the present invention can provide an effect of ensuring a delay time as long as possible even in a narrow space upon outputting a signal related to a conductive state, by virtue of interaction of a main shaft, a pin portion, a first rotating unit, a second rotating unit and a spring member.

摘要： A hydromechanical stored-energy spring mechanism is provided for operating at least one switching contact of a circuit breaker, for example, in a high-voltage switching system. The hydromechanical stored-energy spring mechanism includes a hydraulically operated close-open (CO) delay circuit configured to delay triggering of a switching process of the circuit breaker, and an electromechanical actuator provided in place of a hydraulic operation of the CO delay circuit. The electromechanical actuator generates a mechanical time delay or acceleration over an extended temperature range.

摘要： A parallel pole magnetohydraulic circuit breaker, having a single trip element and a pair of trip mechanisms, achieving an increased current carrying capacity with reduced nuisance trips. The trip mechanisms are contained within separate housings, with electrical connections and multipole trip mechanism communicating through apertures in the common wall. Preferably, the armature of the trip element acts on a single trip mechanism, which multiplies the available force to trigger a trip of the other trip mechanism.

摘要： Disclosed is a snap action circuit breaker with a compact one piece steel frame in a two part, telescoping molded circuit breaker case. The compact construction is combined with a symmetrical toggle actuator to provide a pleasing appearance suitable for mounting at readily accessible and visible locations on the front of an instrument panel. A variety of handle constructions are usable with the same basic mechanism. By providing a snap actuated contact construction with substantial overcurrent trip delay the device combines the best features of modern manual switches and circuit breakers so that it is in effect a manual switch with nuisance free over-current trip protection.

摘要： An electromagnetic circuit breaker comprising a solenoid coil and an armature actuatable by the coil. A tube of nonmagnetic material within which is a movable magnetizable core, the tube having a pole piece at one end toward which the armature is attracted on predetermined overload conditions, the core being biased toward the end of the tube away from the pole piece.An inertial mass is carried by the armature and is pivotally and eccentrically connected to a link at one end. The link has another end pivotally mounted to a fixed support.Thus, when the armature is attracted to the pole piece the inertial mass is caused to rotate at an angular velocity greater than the angular velocity of the armature, so that the current in the coil required to overcome the bias on the armature with substantially no time delay, when the gap between the core and the pole piece is at its maximum, is substantially higher than the current required for a similar device but which omits the inertial mass.
