SMA SBCB-6-3R > 6 Input Combiner Box - NEMA 3R Enclosure
SMA Combiner 6 Circuits 15A NEMA 3R SBCB-6-3R
** Fuses sold separately **
Simplify wiring for added convenience and safety. SMA America’s SB/SC
Combiner Boxes are available in sizes ranging from 6 to 52 PV inputs to
provide greater flexibility and expandability in system design.
Oversized bus-work adds high efficiency and dependability where it’s
needed most. The large NEMA 3R/4 enclosure provides ample room for
conductors which reduces installation time.

Documentation
SMA’s line of SB and SC 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 desi gn mi ni mi zes t he number of c omponent s, r esul t i ng i n t he most robust, easy to install, low cost and reliable combiner boxes in the PV industr y. PV wires are landed directly to individual Touch Safe™ fuse holders. The fuse holder outputs are combined into heavy-duty bus-bar combs where the output wires are connected to over- sized 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 de- energized and removed by opening the Touch Safe™ 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.
