Technical Data

MC4-Compatible Solar Cable Connector

CN4U-C is designed as an MC4-compatible solar cable connector for photovoltaic applications. It is developed to match commonly used PV connection systems and provide secure electrical and mechanical connections in solar installations.

For safety and certification compliance, connectors from the same manufacturer and approved connector combinations should be used within the same PV connection system. Mixing connectors from different manufacturers should only be considered when compatibility has been verified and permitted by the applicable certification requirements.
