Stäubli Original MC4 combines the 4 mm connector platform with MULTILAM contact technology and crimp termination for photovoltaic DC connections. Connector selection must match the exact PV cable cross-section and outer diameter; an MC4-style appearance alone does not establish mating compatibility.
The MULTILAM contact system is designed to maintain a low-resistance electrical interface over repeated thermal and mechanical cycles. The specified connector resistance is below 0.25 mΩ, so cable preparation, crimp quality and correct mating remain part of the finished PV connection rather than separate installation details.
Original MC4 is available for several PV cable cross-sections and cable outer diameters. The connector contact, seal and cable gland therefore have to be selected together with the actual cable. Using the same connector family without matching these dimensions can compromise crimping or sealing.
When correctly assembled and mated, the connector is rated IP65/IP68 for the stated immersion condition. Unmated connectors are only IP2X and should be protected from contamination until the final connection is made.
A connector that looks like MC4 is not automatically an Original MC4 mating partner. For extension leads, retrofit work and replacements, the existing manufacturer and exact connector type should be identified before assembly so the DC interface remains within the intended connector system.
Designed for Residential rooftop PV, Commercial rooftop PV, Utility PV string connections and PV extension cable assemblies.
| Nominal cross section mm² | IEC rated voltage DC V | IEC rated current A |
|---|---|---|
| 2.5 | 1100 | 22.5 |
| 4 | 1100 | 39 |
| 6 | 1100 | 39 |
| 10 | 1000 | 45 |
Connector selection also depends on PV cable outer diameter and the matching Stäubli crimp contact / cable gland variant. Use the exact Stäubli ordering table for the finished assembly.
