This male and female pair uses Stäubli's MULTILAM contact technology, keeping contact resistance low and stable through years on a roof or ground-mounted array. If you want the genuine connector at every joint in the string rather than a copy, this is it.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGenuine Stäubli MC4-Evo 2, the original MC4 connector system\u003c\/li\u003e\n\u003cli\u003eFor 4mm² and 6mm² PV cable (12 and 10 AWG)\u003c\/li\u003e\n\u003cli\u003eRated 1500V DC, 45A on 4mm² and 53A on 6mm² to IEC 62852\u003c\/li\u003e\n\u003cli\u003eMULTILAM contact technology with contact resistance below 0.2 mΩ\u003c\/li\u003e\n\u003cli\u003eIP65 and IP68 (1 m, 168 h) when mated, for permanent outdoor use\u003c\/li\u003e\n\u003cli\u003eOperating range of -40°C to +85°C, UV and ammonia resistant\u003c\/li\u003e\n\u003cli\u003ePositive locking system to prevent accidental separation\u003c\/li\u003e\n\u003cli\u003eTÜV Rheinland certified to IEC 62852 and UL recognised to UL 6703\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the original matters\u003c\/h2\u003e\u003cp\u003eMost of the power your panels produce passes through connectors at some point, and those connectors sit under modules and on rooftops for decades of heat, frost and UV. A poorly made or badly crimped connector can develop rising resistance over time, and that means heat, power loss, and in the worst case a melted joint that's expensive to trace once the roof is finished. Paying for the original connector at install time costs very little compared with tracking down a failed joint later.\u003c\/p\u003e\u003cp\u003eMC4 is Stäubli's own system, and the Evo 2 uses MULTILAM contacts: spring-loaded louvres that keep multiple points pressed against the pin so resistance stays low through thermal cycling. Contacts are tin-plated copper, and the housing is UL94-V0 rated PA.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eUse this pair for solar panel string connections, making up PV extension leads on 4mm² or 6mm² cable, connecting strings to inverters, charge controllers and combiner boxes, or replacing damaged or non-original connectors on an existing array. Suitable for residential, commercial and ground-mounted PV systems up to 1500V DC.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1x Stäubli MC4-Evo 2 female connector (socket) for 4 to 6mm² cable, with contact\u003c\/li\u003e\n\u003cli\u003e1x Stäubli MC4-Evo 2 male connector (plug) for 4 to 6mm² cable, with contact\u003c\/li\u003e\n\u003cli\u003eCable and crimping tool are not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation and safety notes\u003c\/h2\u003e\u003cp\u003eFitting should be carried out by a qualified solar installer or electrician. Crimp the contacts with the tool Stäubli specifies for this contact size, following assembly instructions MA298 from staubli.com. Check your cable's outer diameter suits the connector's cable gland, since an incorrect crimp or a loose gland compromises both the electrical joint and the IP rating.\u003c\/p\u003e\u003cp\u003eNever connect or disconnect under load. Isolate the DC circuit with a suitable DC isolator before working on a string. Mate only with connectors from the Stäubli MC4 family, as mixing brands falls outside Stäubli's certification. Unmated connectors are IP2X only, so fit sealing caps on any left exposed outdoors. The complete installation must use correctly sized cable, suitable overcurrent protection, isolation and surge protection, and comply with BS 7671 and local regulations.\u003c\/p\u003e","brand":"Stäubli","offers":[{"title":"Default Title","offer_id":67595958812960,"sku":"003109","price":4.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-003109-1.webp?v=1790688552","url":"https:\/\/www.ledandsolar.co.uk\/products\/mc4-evo-2-connector-pair-1500v","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
