In the AC3 use category, with a rated circuit voltage of 380V and current of 85A, it handles remote on-off switching and frequent start\/stop control of motors. The coil operates at 230VAC 50\/60Hz, making it compatible with standard European single-phase control circuits.\u003c\/p\u003e\u003cp\u003eThe contactor accepts auxiliary contact blocks and air-delay contact modules for expanded functionality, including AC and DC coil control, reversible coil terminals, and pneumatic timing modules. When combined with a thermal overload relay it forms a complete electromagnetic motor starter with overload protection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3NO main contacts for 3-phase motor switching\u003c\/li\u003e\n\u003cli\u003eAC3 use category — rated for frequent inductive motor load switching\u003c\/li\u003e\n\u003cli\u003e230VAC 50\/60Hz coil voltage for compatibility with standard control circuits\u003c\/li\u003e\n\u003cli\u003eAccepts auxiliary and air-delay contact blocks for expanded wiring options\u003c\/li\u003e\n\u003cli\u003eCable cross-section range: 1–10mm² for flexible conductor sizing\u003c\/li\u003e\n\u003cli\u003eTightening torque: 1.5–2.5Nm for secure terminal connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e40A current rating supports motors up to 18kW at standard three-phase voltages\u003c\/li\u003e\n\u003cli\u003eCompatible with DC and AC coil control modules for versatile installation\u003c\/li\u003e\n\u003cli\u003eReversible coil terminals simplify field wiring in complex panel layouts\u003c\/li\u003e\n\u003cli\u003eSpace-saving DIN-rail mounted control modules reduce panel footprint\u003c\/li\u003e\n\u003cli\u003ePair with a thermal overload relay to create a full electromagnetic starter with overload protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e CKDC2A37\/P7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e 3NO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Motor protection power relay contactor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e 40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating:\u003c\/strong\u003e 18kW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse Category:\u003c\/strong\u003e AC3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage:\u003c\/strong\u003e 230VAC 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Voltage Range:\u003c\/strong\u003e up to 690V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Voltage Range:\u003c\/strong\u003e up to 440VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Cross-Section:\u003c\/strong\u003e 1–10mm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTightening Torque:\u003c\/strong\u003e 1.5–2.5Nm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModular design allows auxiliary contacts and timing modules to be added without replacing the main unit\u003c\/li\u003e\n\u003cli\u003eBroad voltage range (AC up to 690V, DC up to 440V) covers diverse industrial and commercial applications\u003c\/li\u003e\n\u003cli\u003eStandard DIN-rail and panel mounting keeps installation straightforward for qualified electricians\u003c\/li\u003e\n\u003cli\u003ePackage includes 1× CKDC2A37\/P7 relay contactor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Other","offers":[{"title":"Default Title","offer_id":56579021504894,"sku":"525176","price":30.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675201847678.webp?v=1779636889","url":"https:\/\/lynk.gr\/en-us\/products\/relay-contactor-ckdc2a37-p7-18kw-40a-3p-230vac-html","provider":"Lynk.gr","version":"1.0","type":"link"}
