Isolationswächter sichern Stromversorgung

(PresseBox) (Nürnberg, )
Um Isolationsfehler frühzeitig erkennen und beheben zu können, bietet die Siemens-Division Building Technologies jetzt zwei neue Einbaugeräte an: die Isolationswächter 7LQ3 354 und 7LQ3 355.

Dies stellen die Isolationswächter 7LQ3 354 und 7LQ3 355 sicher, indem die Geräte den Isolationswiderstand des ungeerdeten Stromnetzes sowie den Laststrom und die Temperatur eines Transformators überwachen.
