Abstract

Es wird ein Fehlerstrom-Zusatzbauteil für einen gekapsel­ ten Leistungsschalter durch die Ertüchtigung eines Arbeits­ stromauslösers derart geschaffen, daß dieser auslöst, wenn ein entsprechender Fehlerstrom vorhanden ist. Hierzu wird eine gedruckte Schaltung in das Gehäuse des Arbeitsstrom­ auslösers eingebaut, wodurch das Vorsehen eines getrennten Fehlerstrom-Relais entfallen kann. Fehlerstromauslösung und Arbeitsstromauslösung stehen im gleichen Zusatzbauteil zur Verfügung, ohne daß zusätzliche Anbau- und Verdrah­ tungsarbeiten notwendig sind. It becomes a residual current component for a capsule circuit breaker by upgrading a job current release created such that this triggers when a corresponding fault current is present. This will a printed circuit in the housing of the working current trigger built in, thereby providing a separate Residual current relay can be omitted. Residual current trip and shunt release are in the same additional component available without additional mounting and wiring work is necessary.
