MC 4 Connector ( Ningbo)

Description

MC4 Connectors, standing for Multi-Contact 4mm, are industry-standard electrical connectors widely used for connecting solar panels in photovoltaic systems. Engineered to handle high-voltage DC electricity, they feature a secure locking mechanism that only disengages with a special tool, ensuring connections remain tight and safe during harsh outdoor conditions. MC4 connectors are made from UV-resistant and flame-retardant materials, with copper alloy contacts designed for excellent conductivity and corrosion resistance. Their waterproof and dustproof design (rated IP67/IP68) protects junction points from environmental damage, enhancing the longevity and reliability of solar arrays. Available in male and female configurations, MC4 connectors simplify installation, support long string lengths, and improve system safety, making them indispensable components in residential, commercial, and industrial solar power installations.
