MC4-Evo 2 Solar Connector Pair 4-6mm² 1500V Pack of 10 | Stäubli

This is the Original Stäubli MC4-Evo 2 connector, the fitting the MC4 name comes from, supplied as 10 male and 10 female pairs. Each pair is built for 4mm² or 6mm² solar PV cable, rated to 1500V DC, and uses Stäubli's MULTILAM contact technology to keep contact resistance low and stable over years of thermal cycling on a roof or ground-mounted array.

Key features of the MC4-Evo 2 connector pair

• Pack of 10 pairs: 10 male and 10 female genuine Stäubli MC4-Evo 2 connectors
• For 4mm² and 6mm² PV cable (12 and 10 AWG)
• Rated 1500V DC, 45A on 4mm² and 53A on 6mm² to IEC 62852
• 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
• Positive locking system to prevent accidental separation
• TÜV Rheinland certified to IEC 62852 and UL recognised to UL 6703

Why the original connector matters

Most of the power your array produces passes through a connector, and connectors sit under modules and on rooftops for decades of heat, frost, rain and UV. A poorly made or badly crimped joint can develop rising resistance over time, which means heat, power loss and, in the worst case, a melted connector and a fault that is expensive to find once the roof is finished. The MULTILAM contacts in the MC4-Evo 2 use spring-loaded louvres that keep multiple points pressed against the pin, so resistance stays low through years of thermal cycling. Contacts are tin plated copper, and the housing is UL94-V0 rated PA.

Installation notes

Fitting should be done by a qualified solar installer or electrician, crimped with the tool Stäubli specifies for this contact size, following assembly instructions MA298 from staubli.com. Never connect or disconnect under load, and isolate the DC circuit before working on a string. Mate only with other Stäubli MC4 connectors, as mixing brands falls outside the certification. Fit sealing caps to any connector left unmated outdoors, since the unmated rating is IP2X only.
