Eaton 1000V DC switched combiners provide a visible means of disconnect and fuse protection
By Anthony Capkun
March 29, 2013 – Eaton has expanded its line of switched combiners with new solutions for utility-scale PV solar applications. The 1000V direct current (DC) switched combiners incorporate the function of a solar combiner box and separate disconnect, providing a visible means of disconnect and fuse protection in a single enclosure for enhanced safety and simplified installation. The solutions facilitate the combination of multiple inputs from a solar array into a single output, and provide a single-point location to safely isolate the DC side of a PV system closer to the modules. Additionally, the new Eaton switched combiners have integral disconnects that are tested and listed to UL 98B, and the entire switched combiner assembly is tested and listed to UL 1741.
