SMA SCCB-12-4 Sunny Central Combiner 12 Inputs/Nema 4 Enclosure
SCCB-12-4 Sunny Central Combiner 12 Inputs/Nema 4 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-12-4 Sunny Central Combiner 12 Inputs/Nema 4 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 4 industrial enclosures are used in many applications where an occasional washdown occurs or where machine tool cutter coolant is used. They also serve well in applications where a pressurized stream of water will be used. NEMA 4 enclosures are gasketed and the door is clamped for maximum sealing. They have continuous hinges, mounting feet, and padlock hasps.
