The Original MC4 Connector (1000V) is the global benchmark for photovoltaic string wiring. Manufactured by Stäubli Electrical Connectors, these single-contact components are engineered to ensure long-term stability and low contact resistance for solar power systems operating up to 1000V DC.

Key Features

• Advanced Contact Technology: Utilizing proprietary Multilam technology, these connectors maintain constant spring pressure and low electrical resistance. This minimizes power loss and prevents localized overheating at connection points.
• Proven Durability: These connectors are designed to last over 25 years in harsh outdoor environments. They feature high-grade, UV-resistant insulation materials that resist aging and degradation from continuous exposure to sunlight.
• Superior Environmental Protection: Rated at IP68, the connectors provide the highest level of protection against dust and water ingress. When properly mated, they remain watertight even under temporary immersion, ensuring system reliability in rainy or humid climates.
• Secure Connection System: The integrated snap-in locking mechanism provides a physical and audible confirmation of a secure connection. This prevents accidental decoupling due to cable tension or thermal expansion and contraction.
• High Current Capacity: Engineered to handle high current loads, these connectors are suitable for a wide range of cable cross-sections, typically from 4 mm² to 6 mm², making them versatile for various residential and commercial solar arrays.
