    摘要： A circuit breaker/surge arrestor package for plug-in installation in the space of two standard one-inch openings in a contemporary residential load center. The electrical and thermal characteristics of the components are selected such that a threshold of a substantially continuous current through a Metal Oxide Varistor in the surge arrestor causes the circuit breaker to trip magnetically before being able to trip thermally.

    摘要： A protection circuit for a simulated battery cell having an output comprising an output voltage includes: at least one MOSFET connected to the output of the simulated battery cell for short-circuiting the output of the simulated battery cell; a capacitor connected to a gate electrode of the at least one MOSFET; an overvoltage detection device configured to charge the capacitor with the output voltage based on an overvoltage limit of the output voltage being exceeded; and a threshold voltage detection device configured to release the gate electrode based on a threshold value of a voltage at the capacitor not being reached.

    摘要： A disconnector and related surge arrester include first and second connection terminals connecting to active electrical leads, between which a protection element is inserted, having electrodes electrically connected to the connection terminals, a disconnector between the first terminal and an electrode of the protection element including a metal plate having a base end electrically connected to the first terminal and a distal end maintained electrically connected to the electrode, the plate being able to sublimate in the presence of short-circuit currents above a preset threshold, an intercepting slider, mounted longitudinally slidable along a longitudinal direction which lies between the base end of the lamina and the electrode of the protection element to intersect development of an electric arc, a sliding guide for the intercepting slider, the slider being biased in the longitudinal direction, through a preloaded elastic unit, towards an intercepting position abutting a portion of the plate.

    摘要： Surge arrester structure is provided for a dead tank circuit breaker. The circuit breaker has a pole assembly with a first electrical terminal in a first bushing, and a second electrical terminal in a second bushing. The first terminal is electrically connected to a stationary contact and the second terminal is electrically connected to a movable contact. The surge arrester structure includes a surge arrester having first and second opposing ends. A first conductor structure electrically and mechanically connects the first end of the surge arrester with an end of the first terminal. A second conductor structure electrically and mechanically connects the second end of the surge arrester with an end of the second terminal. The surge arrester is electrically connected parallel with respect to the stationary and movable contacts so that the surge arrester can limit transient over voltages occurring across the contacts when the contacts are open.

    摘要： An overvoltage protection apparatus may include a first connection for coupling to an N line, and at least one voltage-limiting element which is designed to block the current through the voltage-limiting element up to a predefinable threshold value of the voltage dropped across the voltage-limiting element and to conduct the current above this threshold value. The overvoltage protection apparatus may further include a second connection for coupling to a metal housing of an electrical apparatus, at least one capacitor, and at least one first non-reactive resistor. The at least one capacitor, the at least one first non-reactive resistor and the at least one voltage-limiting element are connected in series between the first connection and the second connection.

    摘要： A voltage and/or current sensing device for low-, medium- or high voltage switching devices is disclosed as a constructively enhanced measuring device with high performance for use in switching devices. The sensing device can include a first voltage sensing part, a second voltage sensing part and a current sensing part all arranged in a same common single housing separated, from the switching device, in a way that an output wire from the first voltage sensing part, for sensing voltage at an upper terminal of the switching device, is located close to the current sensing part, the output wire being applied with an insulating cover, and mechanically fixed to the current sensor part, and/or the output wire being implemented in an isolation body, and only located near to the current sensing part.
