Product details
WAGO Corporation's 279-620/281-408 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 Feed Through configuration provides essential isolation for photovoltaic system grounding requirements. The double-barrier design prevents galvanic corrosion in outdoor installations.With 4 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 4.0mm wide terminals accommodate thick PV module cables without deformation. The tinned copper construction resists sulfurization in harsh environments.Utilizing Push In, Spring technology, the connection system maintains low contact resistance over 25-year service life. The silver-plated contacts prevent fretting corrosion from vibration.Rated for 500 mA continuous DC current, the terminal exceeds solar array requirements. The thermal design maintains stable performance from -40 C to 85 C ambient.Compatible with 16-28 AWG PV wire, the terminals feature integrated sunlight-resistant boots. The dual-compression design prevents conductor pull-out in windy locations.Integrated Diode enable real-time performance monitoring without additional components. These smart features communicate with system controllers via powerline signaling.The Gray housing incorporates UV stabilizers for 25-year outdoor exposure. The light-reflective surface reduces heat buildup in direct sunlight.
