SC-3MM-100-series enclosures combine critical functionality and capabilities for small-cell/5G applications. Each enclosure is UL 508A service entrance-rated, eliminating the need for a separate disconnect between the cabinet and utility. A 100-amp input breaker provides more than ample capacity for typical installations. Within the cabinet, integrated surge protection enables reliable protection and safe long-term equipment performance with no degradation following surge events. Configurable features include 16-branch circuit breakers for load protection to critical small cell electronics, two additional dual-pole breakers, 24 fiberoptic couplers for distribution, three twisted-pair (copper) couplers, an RJ45 Ethernet interface and a GFCI outlet.
