The single NC contact carries positive opening per IEC 60947-5-1 Appendix K, so it opens mechanically even if the contact surfaces have welded, guaranteeing the stop signal on demand. With one NC contact only, this unit suits a single safety circuit input; choose the XB5AS8445 (1NC+1NO) where the control system also needs a separate monitoring or status signal.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54074884030747,"sku":"XB5AS8442","price":11.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-xb5as8442-harmony-xb5-emergency-stop-push-button.jpg?v=1790851760","url":"https:\/\/stoklink.com\/products\/schneider-electric-xb5as8442-emergency-stop-push-button","provider":"Stoklink","version":"1.0","type":"link"}
