The 48 V DC coil variant fits control circuits already wired at that voltage, so the contactor coil can be driven directly without an additional transformer tap. The DC coil has no inrush surge and a longer 30–40 ms closing time than the AC-coil CA2Kseries, which electronic surge suppression trades for lower steady-state power draw — relevant when the relay is driven from a PLC transistor output or a current-limited 24 V DC rail.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54076966076699,"sku":"CA3KN40ED","price":23.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-ca3kn40ed-tesys-k-control-relay.jpg?v=1790874003","url":"https:\/\/stoklink.com\/products\/schneider-electric-ca3kn40ed-tesys-k-control-relay","provider":"Stoklink","version":"1.0","type":"link"}
