SmartWiring 400A Busbar – 12V–48V DC Power Distribution Block with Cover – M8 Stud, Surface or DIN Rail Mount – for Marine, RV, Car, Truck & Solar System

This SmartWiring 400A busbar is a passive power distribution unit designed for low voltage DC systems (12V–48V). It functions as a reliable connection point — ideal for distributing power or joining circuits together, such as grounding bars in marine, automotive, or solar applications. Also available in 150A, 250A and 600A models — see our other listings for options. Engineered for High Performance and Safety: Efficient Heat Dissipation: The honeycomb-style base maximizes airflow to reduce heat build-up under load. Moisture Protection: Fibre washer stand-offs improve ventilation and reduce the risk of trapped water, minimizing corrosion. High Current Capacity: Optimally sized tinned copper bus bar ensures safe handling of high currents without overheating. Built to strict safety standards, this unit is ideal for marine vessels, RVs, solar setups, trucks, and custom off-grid systems. Avoid low-cost alternatives that may not meet essential performance and safety requirements.
