APC AP4453A NetShelter Rack ATS 2U 120V 30A, 16 5-20R | Rack Mount

Keep critical rack equipment online when primary power is interrupted with the APC NetShelter Rack ATS AP4453A. This 2U automatic transfer switch is built for environments that cannot tolerate a single point of failure at the rack level. With dual L5-30P inputs, it can switch between power sources to help sustain connected loads when one feed drops or becomes unstable. The unit delivers 120 V at 30 A and provides 16 5-20R outlets, giving infrastructure teams a practical way to distribute power across servers, network devices, and supporting equipment. Its 2U form factor fits cleanly into standard rack layouts while preserving enough space for adjacent hardware and cable management. For teams responsible for uptime, the ATS design adds a layer of resilience that a standard PDU cannot provide. AP4453A is a strong fit for edge rooms, branch infrastructure, and enterprise racks where power continuity matters as much as outlet count. It is the kind of component that earns its place by reducing risk, simplifying dual-feed deployment, and helping keep essential systems running through power events.
