SMA Combiner Box, 6 Circuits, 600VDC, NEMA 3R, SBCB 6
String Combiner Boxes
Introducing SMA America's new Sunny Central Combiner Boxes
The Sunny Central Combiner Boxes combiners are available in sizes ranging from 6 to 52 PV input strings to provide greater flexibility and expandability where it's need most. The large NEMA 3R enclosure provides ample room for conductors and will help reduce installation time. Designed with installers in mind, we know you'll find the new Sunny Central Combiner Box a welcome addition to SMA's great line of Sunny Central products.
SMA's new line of combiner boxes is a culmination of many years of experience with the difficulties of combining large numbers of PV strings. This simple component has generally become known as a common point of failure in large PV arrays. The SMA deisgn minimizes the number of components, resulting in the most robust, easy to install, low cost and reliable combiner boxes in the PV industry.
PV wires are landing directly to individual Touch Safe(TM) fuse holders. The fuse holder outputs are combined into heavy-duty bus-bar combs where the output wires are connected to oversized mechanical lugs. All wiring is routed in an orderly manner through the enclosure, minimizing the chance of shorting caused by pinched or abraded wires. Individual PV string circuit fuses may be safely deenergized and removed by opening the Touch Safe(TM) fuse holders. No special tools are required.
Output wires may be paralleled keeping wire sizes small and easy to pull through conduit. Combiner boxes may be paralleled to increase the total number of PV strings. The steel enclosure is rated for outdoor installations and all SMA combiner boxes are ETL listed to UL 1741.
