APC NetShelter Rack Automatic Transfer Switch 1U 15A

The APC AP4450A is a rack-mount automatic transfer switch that keeps single-corded IT equipment powered even when one power source goes down. By drawing from two independent NEMA 5-15P input cords, it silently transfers load to the available source, so switches, servers, and edge appliances continue running without a reboot or user intervention.

Rated for 15 amps at 100 to 120 volts and up to 1440 VA, the unit fits neatly into 1U of rack space, making it a natural choice for network closets, branch offices, and production data centers where space is precious and uptime is critical. Ten rear NEMA 5-15R outlets accommodate a mix of network gear and small servers, while front and rear cord retention clips help keep plugs firmly seated to prevent accidental disconnects.

Local visibility comes from a clear LCD display that shows source status, load level, and alarms. Color LEDs provide at-a-glance confirmation of which input is active. For remote oversight, the factory-installed APC NMC3 network card enables secure access through a Web interface, SNMP, or a command-line session, allowing staff to check loads, set thresholds, and receive alerts from anywhere.

Built for demanding environments, the switch operates in temperatures from -5 °C to 45 °C and humidity up to 95 percent non-condensing. It carries TÜV safety marks and meets FCC Class A requirements for electromagnetic compatibility. All mounting hardware ships in the box, and the standard two-year warranty can be extended to five years for added peace of mind.
