Frequently Asked Questions
It connects solar panels, combiner boxes and inverters in photovoltaic systems with a secure, weatherproof DC connection.
The connector is available in 1000V and 1500V DC versions, with rated currents of 30A, 45A and 65A.
It accepts 4 mm² photovoltaic cable with a Φ4 mm conductor, which covers the common string cable sizes used on rooftop and ground-mount arrays.
IP67 when mated, and IP2X when unmated. The mated assembly is sealed against water and dust ingress.
Yes. The IP67 sealing, UV-resistant PC/PPO housing and salt-mist tested design (IEC 60068-2-52, severity 5) suit permanent outdoor solar installations.
It mates with connectors of the same snap-in locking type. For cross-brand mating, check the mechanical drawing against your existing connector before ordering, and ask us for a sample where the fit is critical.
