Abstract: An electrical protection unit A including a main conductor and, for each main conductor, a current limiter device connected in series with the main conductor to limit the current when a current or temperature threshold is exceeded, the limiter device including an element made of a material having a positive temperature coefficient, called PTC, and being capable of controlling a device for tripping the mechanism M for opening the contacts of the protection unit D, to cause the opening of the contacts of the unit when the threshold is exceeded leading to a change of state of the element between a low resistance state and a high resistance state. The PTC element includes the trip device, in such a way that this element itself provides the functions of fault current limitation and of tripping the mechanism for opening the contacts.

Abstract: An overvoltage protection element with a housing, an overvoltage-limiting component arranged in the housing, and with two connection elements for electrically connecting the overvoltage protection element to the current or signal path to be protected, wherein, normally, the connection elements are each in electrically conductive contact with a pole of the overvoltage-limiting component. Reliable and effective electrical connection in the normal state and reliable isolation of a defective overvoltage-limiting component are ensured by the fact that a thermally expandable material is arranged within the housing in a way that, in the event of thermal overloading of the overvoltage-limiting component, the position of the overvoltage-limiting component is changed by expansion of the thermally expandable material relative to the position of the connection elements in a way that causes at least one pole of the overvoltage-limiting component to be out of electrically conductive contact with the corresponding connection element.

Abstract: An electrical switching device includes a housing, a base attached to the housing, two non-actuated electrical contacts supported in the housing, and an actuator assembly contained within the housing. The actuator assembly includes a movable contact for engaging the non-actuated electrical contact and a wire element formed of a shape memory alloy. Applying an electric current to the wire element causes the actuator to either pivot or rotate the movable contact to either engage or disengage the non-actuated electrical contacts.

Abstract: An improved MEMS thermal actuator has a cantilevered beam and a conductive circuit having two driving arms, an inner arm adjacent to the cantilevered beam, and an outer arm adjacent to the inner arm. Current flows through the inner and outer arms to heat the conductive circuit, causing it to expand relative to the cantilevered beam. A tether ties the conductive circuit to the cantilevered beam, so that upon expansion, the conductive circuit causes the cantilevered beam to deflect about its anchor point. However, only the inner arm of the driving beam is coupled to the cantilevered beam. Since the outer arm of the conductive circuit is not coupled to the cantilevered beam, the overall stiffness of the actuator may be decreased. In addition, serpentines may be placed in the outer arm of the conductive circuit, in order to further decrease the stiffness of this beam. The actuator may therefore be made more efficient, in that the deflection of the cantilevered beam may be increased for a given input current.
Abstract translation: 改进的MEMS热致动器具有悬臂梁和具有两个驱动臂的导电电路，与悬臂梁相邻的内臂以及与内臂相邻的外臂。 电流流过内臂和外臂以加热导电电路，使其相对于悬臂梁膨胀。 系统将导电电路连接到悬臂梁，使得在膨胀时，导电电路使悬臂梁绕其锚点偏转。 然而，只有驱动梁的内臂联接到悬臂梁。 由于导电电路的外臂未连接到悬臂梁，所以致动器的整体刚度可能会降低。 此外，蛇形管可以放置在导电电路的外臂中，以便进一步降低该梁的刚度。 因此，可以使致动器更有效，因为对于给定的输入电流，可以增加悬臂梁的偏转。

Abstract: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.

Abstract: A tripping device (1) for circuit breakers comprising a thermally influenceable wire-shaped tripping element (4) is presented, one end of which is attached to a rotatably supported tripping lever (3) which is under spring force and the other end of which is fixed in location. The thermally influenced lateral movement at one end of the tripping element (4) causes the unlatching of the circuit breaker. At the free end of the tripping lever (3), a locking element (11) is provided which engages a cam (10) of a contact lever (2) which is under spring force, in such a manner that the circuit breaker is switched off both with contraction and with expansion of the tripping element (4).
