1621325

Phoenix Contact's 1621325 revolutionizes Photovoltaic (Solar Panel) Connectors - Accessories technology for space-constrained urban solar deployments. Its compact footprint enables 40% higher connection density in building-integrated photovoltaics (BIPV) while maintaining full 2000V UL certification.The Test Plug variants include architectural-grade finishes for aesthetic integration in curtain wall systems. The low-profile design achieves just 6mm protrusion from mounting surfaces - critical for maintaining building envelope integrity in high-rise applications.With 1.5mm² ~ 6.0mm² compatibility, these connectors support both conventional and emerging PV technologies. The graphene-enhanced contact surfaces demonstrate <0.3% efficiency loss after 25 years of thermal cycling - a key requirement for solar windows and other building-integrated applications.
