TEMCo Industrial Staubli MC4 Solar Connectors Male & Female, 10 Pairs — IP68, 1500V/50A

These Staubli MC4 male and female solar connectors (10 pairs) provide weatherproof, high-current PV connections for 10–12 AWG cables in residential and commercial solar systems.

Designed for outdoor photovoltaic wiring, TEMCo Industrial supplies genuine Staubli MC4 connectors that accept 5.5–7.4 mm cable diameters (compatible with TEMCo 10 or 12 AWG PV cable). The pair set includes durable male and female housings and copper MULTILAM terminals engineered for low contact resistance and secure snap-in locking. When mated they reach IP65/IP68 protection levels for reliable dust and water resistance, and they’re rated for up to 1500 VDC and currents up to 50 A — suitable for modern PV arrays and on-site renewable installations.

How do these connectors hold up outdoors?

Staubli MC4 housings are molded for UV and weather resistance and the sealed design prevents contaminants from entering when connectors are joined. The engineered snap-lock keeps the pair from vibrating apart in wind or mechanical strain, while the MULTILAM terminals maintain a stable electrical path over repeated use.

• IP65/IP68 rating when mated — dust-tight and waterproof under immersion conditions
• UV-stable housing material for prolonged sunlight exposure
• Snap-in locking mechanism for vibration resistance
• Made to withstand outdoor thermal cycling without degrading contacts

What cable and tools are required for installation?

These MC4 connectors accept PV cables with outer diameters from 5.5 mm to 7.4 mm, which corresponds to common 10 or 12 AWG solar cables. Proper crimping of the copper MULTILAM terminals is necessary for a secure electrical and mechanical joint — a specific solar crimping tool is recommended for consistent results.

• Compatible with TEMCo 10 AWG or 12 AWG PV cable and equivalent 5.5–7.4 mm diameter cables
• Requires a solar cable crimping tool; recommended TEMCo TH0011 (sold separately)
• Strip length and crimp depth follow manufacturer guidance for the best seal
• Suitable for field or factory termination when installed correctly

Are these connectors safe for high-voltage or high-current arrays?

Staubli MC4 connectors meet common photovoltaic system demands, rated up to 1500 VDC and carrying currents up to 50 A when installed with correct cable and tooling. The MULTILAM terminal design minimizes contact resistance, reducing heat buildup at the connection under load.

• Voltage rating: up to 1500 VDC for modern PV strings
• Current capacity: up to 50 A depending on conductor size and installation quality
• Low-contact resistance via MULTILAM technology improves long-term performance
• Proper installation needed to realize full voltage/current ratings

How do I maintain or inspect these connectors over time?

Routine visual inspections and periodic electrical checks help ensure continued reliability. Look for secure locking, clean contacts, and intact seals; replace any connector with visible damage or corrosion to preserve system safety and efficiency.

• Inspect mating latch and housing for cracks or deformation
• Verify seals and gaskets remain in place and free of dirt
• Test for voltage drop or unexpected heating under load during maintenance
• Replace individual terminals or housings if corrosion or wear is evident

Who is this for: These Staubli MC4 male and female connector pairs suit electricians, solar installers, and DIY system builders who need UL-style, field-terminable PV connections that resist weather and carry modern array voltages and currents. They’re ideal for residential rooftop systems, ground-mounted commercial arrays, and any outdoor renewable energy project that requires dependable, sealed connector pairs — provided you use the proper crimp tool and follow installation guidelines.
