The 110 V AC coil variant fits control circuits already wired at that voltage, so the contactor coil can be driven directly without an additional transformer tap. The AC coil pulls in within 10–20 ms and draws 30 VA at inrush, dropping to 4.5 VA hold-in, which is the standard figure to size a shared control transformer against when several of these relays switch together.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54076972302619,"sku":"CA2KN31F7","price":17.71,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-ca2kn31f7-tesys-k-control-relay.jpg?v=1790874097","url":"https:\/\/stoklink.com\/products\/schneider-electric-ca2kn31f7-tesys-k-control-relay","provider":"Stoklink","version":"1.0","type":"link"}
