Die Wechselstromschütze der Serie EKC2SU dienen zur Steuerung von Drehstrommotoren bis 690 V AC. Diese Schütze sind in Blockbauweise mit drei Hauptpolen ausgeführt. Ein integrierter Hilfskontakt (1 Öffner + 1 Schließer) und ein Überspannungsschutz reduzieren Installationszeit und -kosten.
Im Vergleich zu Schützen mit externen Überspannungsableitern bieten Schütze mit eingebauten Überspannungsableitern eine zuverlässigere Leistung. Gleichzeitig werden die Überspannungen vom Schütz selbst abgefangen und erreichen niemals den Steuerstromkreis.
Warum ist ein Überspannungsschutz für Wechselstromschütze erforderlich?
Wechselstrom-Schützspulen sind von Natur aus induktiv. Beim Abschalten der Spule entsteht eine hohe transiente Spannung, die elektromagnetische Störungen verursachen und elektronische Steuergeräte elektrisch belasten kann.
Um einen zuverlässigen Betrieb in industriellen Steuerungssystemen zu gewährleisten, verfügt der Schütz über einen integrierten RC-Überspannungsschutz, der direkt an die Spulenanschlüsse (A1–A2) angeschlossen ist. Dieser Schutz begrenzt die Abschaltüberspannung der Spule, verbessert die elektromagnetische Verträglichkeit (EMV) und schützt empfindliche Steuerausgänge wie SPSen und Halbleiterschnittstellen. Dadurch ermöglicht der Schütz einen stabilen Langzeitbetrieb auch unter anspruchsvollen industriellen Bedingungen.
