Im stromlosen Zustand bleiben die Kontakte im Schlie\u00dfer-Modus, und die Stifte 30 und 87 sind nicht verbunden; wenn die Nennspannung an die Spulenklemme angelegt wird, arbeitet der elektromagnetische Mechanismus, um die beweglichen und statischen Kontakte zu schlie\u00dfen, und die Stifte 30 und 87 leiten, um einen Stromkreis zu bilden. Nach einem Stromausfall stellt der Federr\u00fcckstellmechanismus automatisch den Schlie\u00dferzustand wieder her und sorgt f\u00fcr eine schnelle Unterbrechung des Stromkreises.<\/p>\n\n\n\n<h3><a href=\"https:\/\/topfastpcba.com\/de\/5-pin-relay\/\">Was ist ein 5-poliges Relais?<\/a>?<\/h3>\n\n\n\n<p>Bei dem f\u00fcnfpoligen Relais handelt es sich um ein elektromagnetisches Relais mit einpoligem Umschalter (SPDT), das durch die synergetische Wirkung der Steuerklemmen (85, 86) der Spule und der Kontaktklemmen (30, 87, 87a) bidirektionale Schaltvorg\u00e4nge erm\u00f6glicht.<br>Im Vergleich zu vierpoligen Relais k\u00f6nnen f\u00fcnfpolige Relais mit ihrer Zweikreis-Schaltf\u00e4higkeit und ihren Zustandsr\u00fcckf\u00fchrungseigenschaften komplexere Steuerungsanforderungen erf\u00fcllen und werden h\u00e4ufig in elektrischen Systemen eingesetzt, die ein Schalten in mehreren Zust\u00e4nden oder Fehlerschutz erfordern.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Structural_Design_and_Functional_Differences\"><\/span><strong>2.
