Qoltec MC4 Y-Type Solar Branch Connector Pair 1000V 30A IP67

MC4-compatible Y-type branch connector pair for high-current parallel connections in photovoltaic systems. Splits a single input into two outputs or combines two strings, delivering 30A at 1000V DC with an IP67 weatherproof seal and UL94-V0 flame-retardant housing.

Advantages

Built with tinned copper contacts and PPO insulation, this connector set minimizes contact resistance to ≤0.5 mΩ while withstanding extreme temperatures from -40°C to +90°C. The crimp connection ensures a durable, gas-tight joint, and the pair includes both M/FF and F/MM configurations for versatile wiring. Rated for over 20 years of service life, it carries TUV and CE certifications for reliable performance in demanding solar installations.

Suitable for

• Parallel connection of solar panels in residential and commercial PV arrays
• Combining multiple panel strings before the inverter
• Outdoor solar installations exposed to rain, dust, and UV radiation
• Use with 2.5mm², 4mm², or 6mm² solar cables (14-10 AWG)
