Staubli Branch Connectors, often referred to as MC4-Y connectors, are premium solar components designed for the safe and efficient parallel connection of photovoltaic strings. These connectors allow for the combination of two DC strings into a single output, significantly reducing the amount of cable required and simplifying the wiring architecture of residential and commercial solar arrays.

Key Features

• Parallel String Integration: These connectors enable the parallel connection of PV modules or strings without the need for additional combiner boxes in smaller configurations. This reduces system complexity and installation time.
• Original Multilam Technology: Built with Staubli’s proprietary contact system, these branch connectors ensure low contact resistance and high reliability. This technology minimizes power loss and prevents heat buildup at the connection points.
• Plug-and-Play Compatibility: They are fully compatible with the standard MC4 and MC4-Evo 2 connector families, ensuring a secure and standardized connection across the entire photovoltaic system.
• Weatherproof Durability: Rated at IP67, these connectors are designed to withstand harsh outdoor conditions, including heavy rain, snow, and extreme UV exposure, maintaining a service life of over 25 years.
• Vibration-Proof Locking: The integrated snap-in locking system provides a physical and audible confirmation of a secure connection, preventing accidental decoupling due to wind-induced vibration or thermal expansion.
