| PURPOSE: A circuit breaker is provided to perform a voltage endurance test on the leakage breaker safely by separating a leakage detection circuit from a main circuit. CONSTITUTION: A circuit breaker protects against an over-current and a ground failure. The circuit breaker includes a main-body case, a main node, a switch(3), an operating handle(4) attached to the switch for operating the switch, an over-current tripping device(5) disposed in the main-body case, and a leakage-detection circuit(7) combining the over-current tripping device with a zero-phase current changer(6). The circuit breaker includes a power-supply circuit connected between the leakage-detection circuit and the main circuit for supplying a voltage of the main circuit to the leakage-detection circuit. A test switch(21) is disposed in the main-body case for turning on and off the power-supply line when the switch turns on and off the main node. | ||||||

| PURPOSE: A manual call point is provided to be capable of obtaining the capacity to function and readiness of which is monitored from the control center, and which has a simple construction and is produced economically by using a pivoting lever. CONSTITUTION: A manual call point comprises a housing base(1), an alarm insert, a printed circuit board(3), a switching element(6) and an actuating mechanism. The alarm insert includes a side wall(2), a fragile panel(4) held at a distance from the printed circuit board(3) and a printed protective film(5). The switching element(6) includes a sprung-end switch. The actuating mechanism which serves to actuate the switching element(6) is formed by a pivoting lever(7) resting on a lateral edge of the fragile panel(4). The manual call point is equipped with a device to trigger a test alarm. This consists of a switching lever(9) to displace the panel(4) into a position in which the pivoting lever(7) is released, and a key(10) which actuates the switching lever(9). | ||||||

Es wird eine Vorrichtung (700) und ein Verfahren zum manuellen Auslösen einer Gefahrmeldung beschrieben. Die Vorrichtung (700) weist ein Chassis (706) und ein Schaltelement (710) auf, welches innerhalb des Chassis (706) angeordnet ist. Das Schaltelement (710) ist ein einstückiges Element. Das Schaltelement (710) ist derart ausgebildet, dass es durch eine Auslösebewegung von einem ersten räumlichen Zustand in einen zweiten räumlichen Zustand überführbar ist. Dabei ist der erste räumliche Zustand dafür indikativ, dass mit der Vorrichtung (700) keine Gefahrmeldung ausgelöst wurde, und der zweite räumliche Zustand ist dafür indikativ, dass mit der Vorrichtung (700) bereits eine Gefahrmeldung ausgelöst wurde. Die Vorrichtung (700) kann zusätzlich eine optische Anzeigeeinrichtung (760, 766) zum Anzeigen der Information aufweisen, ob bereits eine Gefahrmeldung ausgelöst wurde. Dabei kann die optische Anzeigerichtung ein transparentes und strukturiertes Alarmanzeigeelement (760) aufweisen, welches abhängig von dem räumlichen Zustand des Schaltelements (710) mit einem optischen Indikatorelement (766) in mechanischem Eingriff gebracht werden kann, so dass sich für eine Bedienperson die optische Erscheinung des Alarmanzeigeelements (760) ändert.

Bei einer linearen Verschiebung des vorderen Elements wird die Alarmanzeige des hinteren Elements sichtbar. Vorzugsweise bildet das vordere Element integralen Bestandteil des Auslöseelements (9) und wird bei dessen Verstellung bei Betätigung des Notrufschalters oder bei dessen Rückstellung nach einer Betätigung verschoben. Das Auslöseelement (9) ist durch einen verschiebbaren Schlitten gebildet und federnd gegen eine Wippe (20) gedrückt.

| A normally open thermal switch (200) having a bimetallic disk (18) is configured for operational testing in its installed position when exposed to a changing temperature by a test box (400) having a power source (400a). The in-place testing advantageously confirms triggering action of the switch by an event indicator (400c) at the operational temperatures designed into the switch (200). The temperature of the triggering action is presented on a temperature display (400b) and recorded by a data recorder (400d) of the test box (400). The switch (200) incorporates a heating element (24c) to heat changing the bimetallic disk (18) to snap activate at the operative temperatures. The thermal switch (200) is coupled with the test box (400) to confirm its operation without having to remove the switch from its installed location. | ||||||
