xStäubli MC4-Evo 2 Solar Connector Pair 10mm² 1500V Original MC4
The Original Stäubli MC4-Evo 2 10mm² pair is built for heavy DC cable, where a standard 4mm² or 6mm² connector simply will not fit. Rated to 1500V DC and 69A, with Stäubli's MULTILAM contact technology, it gives long DC runs and high current circuits a genuine MC4 termination with consistently low contact resistance.
Key Features
- Genuine Stäubli MC4-Evo 2, the original MC4 connector system
- For 10mm² PV cable (8 AWG)
- Rated 1500V DC and 69A to IEC 62852, 70A to UL 6703
- Cable gland for 6.4 to 8.4 mm cable outer diameter on both halves
- MULTILAM contact technology with contact resistance below 0.2 mΩ
- IP65 and IP68 (1 m, 168 h) when mated, for permanent outdoor use
- Operating range of -40 °C to +85 °C, UV and ammonia resistant
- TÜV Rheinland certified to IEC 62852 and UL recognised to UL 6703
Product Overview
10mm² cable is normally chosen for long DC runs, where a larger conductor keeps voltage drop and cable losses down, or for circuits carrying higher currents. The connectors at each end then need to match that cable: the right contact size for the conductor and the right gland for the thicker insulation. Both halves of this pair take cable with an outer diameter of 6.4 to 8.4 mm.
A connector carrying 60A or more has little margin for a poor joint. Any rise in contact resistance becomes heat quickly, and a failed connector on a main DC run can take a whole array offline. MC4 is Stäubli's own connection system, and the MC4-Evo 2 uses MULTILAM contacts, spring-loaded louvres that keep many contact points pressed against the pin, so resistance stays low and stable through years of thermal cycling.
The copper contacts are tin plated, the housing is UL94-V0 rated PA, and the mated connection is rated IP65 and IP68, suitable for outdoor installation under modules, on roofs and on ground-mounted arrays.
Applications
- Long DC cable runs from the array to the inverter or combiner box
- Higher current PV circuits that call for 10mm² cable
- Making up 10mm² PV extension and home-run leads
- Commercial rooftop and ground-mounted PV systems up to 1500V DC
- Replacing damaged or non-original connectors on 10mm² cable
What Is Included
- 1x Stäubli MC4-Evo 2 female connector (socket) for 10mm² cable, with contact
- 1x Stäubli MC4-Evo 2 male connector (plug) for 10mm² cable, with contact
- Cable and crimping tool are not included
Installation and Safety Notes
Installation should be carried out by a qualified solar installer or electrician. The 10mm² contact needs a crimping tool specified by Stäubli for this contact size; tools made for 2.5 to 6mm² contacts are not suitable. Follow Stäubli assembly instructions MA298, available from staubli.com, and check that your cable outer diameter falls within 6.4 to 8.4 mm so the gland seals correctly.
Never connect or disconnect under load. Isolate the DC circuit with a suitable DC isolator before working on any string. Mate only with connectors from the Stäubli MC4 connector family, as mixing brands is not covered by Stäubli's certification. Unmated connectors are IP2X only, so fit sealing caps to any connector left unmated outdoors. The complete system must use correctly sized cable, suitable overcurrent protection, isolation and surge protection, and comply with BS 7671 and local regulations.
