摘要： A wiring device including an interrupting device, a fault detection circuit, and a testing circuit. The interrupting device electrically connects a line terminal to a load terminal when the interrupting device is in a reset condition and disconnects the line terminal from the load terminal when the interrupting device is in a tripped condition. The fault detection circuit is configured to detect a fault condition and generate a fault detection signal in response to detecting the fault condition, the fault detection signal is provided to the interrupting device to place the interrupting device in the tripped condition. The testing circuit is configured to determine a frequency of an input voltage at the one or more line terminals, perform a first test of the interrupting device at a first period of the frequency, and perform a second test of the fault detection circuit at a second period of the frequency.

摘要： A circuit breaker (10) having a movable upper blade (16) with a free floating pivot end (46). The operating mechanism (34) is solidly connected to the upper blade (16). The contact force is generated by a contact spring (44) which exerts an upward force on the lower blade (26). As the contacts (18, 22) separate, the force exerted on the upper blade (16) is virtually eliminated, reducing substantially the resistance at the pivot end (46) of the upper blade (16). The load terminal (12) and pivot end (46) of the upper blade (16) provide a current path parallel to that of the load side flexible connector (15).

摘要： Ein Installationsschutzschalter besitzt in einem Gehäuse (30) eine Überstrom- und vorzugsweise auch eine Fehlerstromauslösung. Das Gehäuse ist in Form von nebeneinander angeordneten Schaltfluchten für die Phasenleiter (L 1, L 2, L 3) und den Neutralleitern (N) ausgeführt, in denen Anschlußklemmen, Kontakte (31) für die Unterbrechung der Phasenleiter und des Neutralleiters, das Schaltschloß (33) mit den thermischen und magnetischen Auslösern (32a. 32) und ggf. Spulen zur Kontaktabhebung sowie bei einer Fehlerstromfassungseinrichtung eine elektronische Verstärkereinrichtung oder ein elektromagnetischer Fehlerstromauslöser mit Summenstromwandler und einer Prüfeinrichtung untergebracht sind. Damit durch den Installationsschutzschalter zu schützende elektronische Bauelemente zusätzlich auch noch gegen Überspannungen geschützt werden können, sind kaskadenförmig auf die Richtung des Energieflusses bezogen für jeden Phasenleiter zwei Überspannungsableiter (40, 41) zusätzlich im Gehäuse (30) des Installationsschutzschalters angeordnet. Einer der Überspannungsableiter (40) befindet sich vor der Spule (32) des elektromagnetischen Auslösers. Der zweite Überspannungsableiter (41) hinter der Spule. Die beiden Überspannungsabieiter sind so aufeinander abgestimmt, daß derjenige Überspannungsableiter (41), der hinter der Spule sitzt, zuerst anspricht und die geringere Energieabsorption aufweist, wogegen der vor der Spule sitzende Überspannungsableiter (40) eine größere Ansprechzeit und eine höhere Energieabsorption besitzt.

摘要： The invention relates to design of protection feature in a self powered protection relay. It specifically provides a relay with sensitive earth fault protection. This protection is being achieved in tandem with optimal power on trip time (switching to fault) and with integrated logic for inrush discrimination. The self supplied protection relay is provided with a current processing module adapted to measure and evaluate line current to generate trip signal. The current processing module has the capability of inrush current suppression to block earth fault detection during an inrush condition and thereby increase sensitivity of fault detection.
