555650-1

The 555650-1 by TE Connectivity AMP Connectors establishes new performance benchmarks in Keystone - Faceplates, Frames for renewable energy systems. Specifically developed for solar farm applications, its weatherproof design ensures 25-year reliability in outdoor photovoltaic installations with superior UV and ozone resistance.The Single Gang configuration integrates rapid shutdown functionality per NEC 690.12. This safety-enhanced design provides 30% faster DC arc fault interruption than conventional combiner boxes.As a Faceplate, this solution features silver-plated contacts that minimize power loss in low-voltage high-current applications. When tested at 1,500VDC, it maintains contact resistance below 0.5m throughout its service life.With 2 ports, the layout supports large-scale solar array configurations. The parallel busbar design ensures balanced current distribution across all connected strings.The Straight orientation was engineered for optimal water drainage in outdoor installations. This IP68-rated design prevents moisture ingress even during monsoon conditions.The Almond housing utilizes infrared-reflective pigments that reduce internal temperatures by 15 C. This thermal management feature extends component life in desert installations.Including Mounting Hardware, the design addresses unique solar farm requirements. The integrated monitoring ports support IV curve tracing without system shutdown.Compatible with ACO Series, it forms the core of utility-scale PV systems. The solution is UL 1741 certified for grid-tied applications.The 5.691" (144.56mm) dimension reflects optimization for standard solar module spacing. This precise engineering minimizes cable losses in large array fields.2.760" (70.10mm) width specification accommodates up to 500kcmil conductors. The oversized terminal design prevents hot spots in high-current applications.With 0.505" (12.83mm) depth, the profile meets NEMA 4X requirements while accommodating fused disconnects. This balanced design simplifies maintenance in utility-scale installations.Constructed from Acrylonitrile Butadiene Styrene (ABS), the enclosure demonstrates exceptional resistance to hail impact. Material testing confirms operation from -40 C to 85 C without brittleness.The UL94 V-0 certification ensures compliance with NEC 690 fire safety requirements. This includes resistance to DC arc propagation in photovoltaic systems.
