APC AP4431 Rack ATS 208 V 30 A 2 L6-30P In 1 Out | Rack ATS, Enterprise

Keep critical rack equipment powered through source changes with an automatic transfer switch designed for dual-feed environments. The APC AP4431 Rack ATS supports 208 V operation at 30 A, giving it the capacity needed for higher-density rack deployments where power continuity is not optional. Two L6-30P inputs and one L6-30R output provide a direct, rack-friendly connection model for controlled distribution. That makes it a strong fit for infrastructure teams that want redundancy at the rack boundary without introducing unnecessary complexity into the power chain. When the preferred source is interrupted, the ATS helps maintain service by shifting to the alternate feed. This model is well suited to environments where downtime has a real cost: server rooms, network aggregation racks, and edge sites with dual power availability. Compared with basic distribution hardware, it adds the transfer logic needed to protect connected loads from a single feed failure. For teams standardizing on dependable rack power, the AP4431 offers a practical balance of capacity, source redundancy, and installation clarity.
