Abstract

Der elektrischer Schutzapparat enthält einen oder mehrere Schalterpole. Diese Schalterpole weisen in einem Apparategehäuse (1') angeordnet jeweils zumindest zwei Stromanschlüsse (31', 32'), einen Stromsensor (33'), einen Auslöser (34') und eine Kontaktanordnung (35') auf. Das Apparategehäuse enthält ferner ein Schaltschloss (4') und ist gebildet von einem Bodenmodul (2'), einem Haubenmodul (5') sowie einem oder mehreren modularen Mittelteilen (3'), welche jeweils die Stromanschlüsse, den Stromsensor, den Auslöser und die Kontaktanordnung eines der Schalterpole aufnehmen. Das bzw. die Mittelteile (3') ist bzw. sind unter Bildung einer Sandwichstruktur zwischen dem Boden- (2') und dem Haubenmodul (5') angeordnet.The electrical protection device contains one or more switch poles. This Switch poles each have at least one arranged in an apparatus housing (1 ') two power connections (31 ', 32'), a current sensor (33 '), a trigger (34') and a contact arrangement (35 '). The apparatus housing also contains a Switch lock (4 ') and is formed by a floor module (2'), one Hood module (5 ') and one or more modular middle parts (3'), which the power connections, the current sensor, the trigger and the Pick up the contact arrangement of one of the switch poles. The middle part (3 ') is or are forming a sandwich structure between the bottom (2 ') and the hood module (5 ') arranged.

Dieser Schutzapparat kann bereits während der Fertigung bei noch offenem Apparategehäuse geeicht und geprüft werden. In mehrpoliger Ausführung wird nur ein Schaltschloss (4') für alle Schalterpole benötigt und kann zudem preiswert gefertigt werden, da die einzelnen Schalterpole jeweils in kostengünstig herzustellenden und zu prüfenden Mittelteilen angeordnet sind.

Figure 00000001
This protective device can already be calibrated and checked during manufacture with the device housing still open. In a multi-pole version, only one switch lock (4 ') is required for all switch poles and can also be manufactured inexpensively, since the individual switch poles are each arranged in middle parts that are inexpensive to produce and test.
