ATFL4220Y

Amphenol PCD's ATFL4220Y revolutionizes Terminal Blocks - Din Rail, Channel technology for renewable energy systems. The corrosion-resistant design and high-current capacity make it perfect for solar arrays, wind turbines, and energy storage applications.The Disconnect, Feed Through configuration provides essential isolation for photovoltaic system grounding requirements. The double-barrier design prevents galvanic corrosion in outdoor installations.The Fuse, Lever safety feature enables rapid shutdown compliance for PV systems. The visible air gap provides positive isolation verification for maintenance crews.With 2 parallel connection points, the terminal block supports high-current combiner box applications. The balanced current distribution design minimizes hot spots.The 1 tiered architecture separates DC and monitoring circuits in renewable energy systems. This arrangement prevents EMI from power lines affecting sensitive instrumentation.The 8.0mm wide terminals accommodate thick PV module cables without deformation. The tinned copper construction resists sulfurization in harsh environments.Utilizing Screw technology, the connection system maintains low contact resistance over 25-year service life. The silver-plated contacts prevent fretting corrosion from vibration.Rated for 6.3 A continuous DC current, the terminal exceeds solar array requirements. The thermal design maintains stable performance from -40 C to 85 C ambient.With 500V DC voltage rating, the component handles both residential and commercial-scale PV systems. The tracking resistance exceeds 600V for reliable operation in polluted environments.UL-recognized for 6.3 A operation, the terminal block meets NEC requirements for solar applications. The flame-retardant housing prevents fire spread.Listed for 220V per UL 6703, the component exceeds utility-interconnection standards. The impulse withstand rating protects against lightning-induced surges.Compatible with 10-22 AWG PV wire, the terminals feature integrated sunlight-resistant boots. The dual-compression design prevents conductor pull-out in windy locations.Integrated LED enable real-time performance monitoring without additional components. These smart features communicate with system controllers via powerline signaling.The Yellow housing incorporates UV stabilizers for 25-year outdoor exposure. The light-reflective surface reduces heat buildup in direct sunlight.Designed for 5mm x 20mm, 5mm x 25mm DC fuses, the protection system meets NEC rapid shutdown requirements. The arc-quenching design safely interrupts fault currents up to 20kA.
