Cimco PV-MC4 Y-Branch Connector MMF 18 005 (180005)

In photovoltaic installations, joining two panel strings into a single feed-in line often requires multiple connectors and extra cable runs. The Cimco PV-MC4 Y-Branch Connector MMF 18 005 solves this by providing a compact, weatherproof branch point that merges two male MC4 inputs into one female MC4 output, reducing wiring complexity and potential failure points.

Who is it for

Solar installers and PV system integrators who need a reliable, TÜV-certified Y-connector for parallel string connections in residential or commercial arrays.
