New Eaton Switched Combiner Enhances Safety, Simplifies Installation for Utility-Scale Solar Applications
Date: March 28, 2013
PITTSBURGH … Diversified industrial manufacturer Eaton has expanded its line of switched combiners with new solutions for utility-scale PV solar applications. The new 1000 volt (V) 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, convenient enclosure for enhanced safety and simplified installation.
“Eaton’s switched combiners are part of our broad offering of balance of system solutions for utility-scale solar applications,” said John Alexander, product manager at Eaton. “They have a visible means of disconnect for enhanced safety, which means that operations and maintenance personnel can see that the blades are disengaged when the switch is turned off.”
The 1000V DC switched combiner 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. The switched combiner design meets the intent of the National Electrical Code (NEC) 690.16(B) – providing the ability to disconnect all sources from the fuse holders so that the fuses can be serviced. Additionally, the new Eaton switched combiners have integral disconnects that are tested and listed to Underwriters Laboratories® (UL) 98B standard, and the entire switched combiner assembly is tested and listed to the UL 1741 standard.
Like Eaton’s heavy-duty safety switch solutions used in utility projects and commercial construction, the 1000 V DC switched combiner incorporates a side-handle operation mechanism and visible means of blade indication that have decades of successful installation and operation.
