SMA SCCB-28 Sunny Central Combiner 28 Inputs/3R Enclosure
SCCB-28 Sunny Central Combiner 28 Inputs/3R Enclosure
Introducing SMA America's SCCB Combiner Boxes. The SCCB combiners are available in sizes ranging from 6 to 52 PV inputs to provide greater flexability 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. Designed with installers in mind, we know you'll find the new SCCB Combiner Boxes a welcome addition to our great line of inverter products.
Features of the SMA SCCB-28 Sunny Central Combiner 28 Inputs/3R Enclosure:
- Greatly simplifies input and output wiring
- Available in 6 to 52 circuit configurations
- Compact, rugged low cost design
- Reliable bus-work for efficient high current conductor combining
- PV positive wires all land directly on Touch Safe™ fuse holders
- Sturdy NEMA 3R/4 wall mount steel enclosure
- ETL Listed to UL 1741
- NEMA 3R electrical enclosures are typically used in outdoor applications for wiring and junction boxes. This style of weatherproof enclosure provides protection against falling rain, sleet, snow, and external ice formation. Indoors they protect against dripping water. This style of enclosure does not have a gasketed sealing surface. Some models have hasps for padlocking.
