Feature → Business Impact → Application: The 200 A amperage rating with two circuits ensures reliable, code-compliant isolation for solar PV runs, reducing the risk of arc flash and enabling safer maintenance windows across multiple strings. This directly improves site safety and uptime, especially for midscale to large solar deployments that demand rapid shutoff during faults or servicing. Application: DCU2064FRM is well suited for solar installations needing a two-pole disconnect with fusible protection, delivering predictable performance under fault conditions and meeting field wiring expectations for LC/SR/EG main lugs. The business impact is lower outage duration, simpler compliance reporting, and reduced maintenance costs over the system life.
