Multi-Contact has extended its range of MC4 solar power connectors to accept 10 mm² cables. With photovoltaic installations becoming larger, cables with greater cross-sectional area are increasingly being used, as they have lower resistance and therefore reduced power losses, particularly at high currents.

The heavy duty MC4 connectors incorporate Multilam technology, which ensures high reliability. They can carry up to 43 A at 1000 Vdc, and have an operating temperature range of -40 degC to +90 degC. Their environmental protection rating is IP67 when mated.

"These connectors are the first 10 mm² photovoltaic connectors on the market that are certified to the latest EN 50521 standard," said Multi-Contact UK managing director Selwyn Corns.

MC4 photovoltaic connectors include a safety clip that requires a tool to unlock. The system enables easy cabling of solar panels either at the factory or on-site.
