Staubli Mc4 Connectors

Upgrade your photovoltaic (PV) solar installations with authentic Stäubli MC4 Y-Branch Connectors, designed for high-efficiency parallel connections of solar modules and panel strings. Engineered with high-grade, weather-resistant materials, these branch connectors provide a secure, plug-and-play solution without requiring custom junction boxes or complex field wiring.

• Patented MULTILAM Technology: Engineered with Stäubli’s signature contact design to ensure exceptionally low contact resistance, minimal power loss, and long-term thermal stability under continuous DC loads.
• Dual-Branch Parallel Coupling: Simplifies the parallel wiring of two PV strings into a single output line while maintaining stable conductivity across all branch points.
• Industrial Weatherproof Housing: Made from UV-resistant, flame-retardant (UL94-V0) engineering plastic with IP68 ingress protection (when mated) to withstand severe outdoor environments, rain, dust, and temperature extremes (-40°C to +85°C).
• Tool-Locked Snap-In Safety: Features an integrated locking latch system compliant with NEC and IEC safety standards, preventing accidental disconnects under high DC voltage.
• Universal Compatibility: Plugs seamlessly into original Stäubli MC4 and MC4-Evo connectors for residential, commercial, and utility-scale solar arrays.
