Flame-retardant housing: PPO insulation material with UL 94-V0 flame class.
Touch-safe design: safety class II.
Wide temperature range: ambient operation from -40°C to +85°C.
Standard 4mm pin: Ф4mm pin dimensions for compatibility with common solar cable terminations.
Standard reference: IEC 60068-2-52.

Commercial Applications of MC4T

In commercial and utility-scale photovoltaic projects, the PV-EKB2 mc4 t branch connector lets installers merge parallel string outputs without cutting cables or adding extra combiner hardware. A mc4 2 to 1 layout reduces the number of home-run cables, simplifies string wiring on rooftops and ground-mount arrays, and speeds up on-site installation.

Applications & Use Cases

Parallel connection of two PV strings or modules into one output cable.
Commercial and industrial rooftop solar systems.
Ground-mounted solar farms and carports.
Solar DC combiner and inverter input wiring.
Expanding or retrofitting existing arrays where an mc4 2 to 1 connector is needed to add a string.
Outdoor installations that require IP67 sealing and a -40°C to +85°C operating range.
