NetShelter ATS 12-outlet 230V 10A

The APC AP4421A is a rack-mounted automatic transfer switch that provides redundant power to connected equipment by switching between two independent sources. It accepts a C14 inlet and distributes power through twelve IEC 60320 C13 outlets rated for 230 V AC at 10 A. The unit is designed for server racks and cabinets where continuous uptime is required.

Passive operation with dual-source switching

The transfer switch contains no active cooling components and operates silently within the rack environment. It draws negligible power for its internal relay logic while passing up to 10 A to the attached loads. Automatic transfer between primary and secondary feeds occurs without interruption to the connected devices.

Twelve C13 outlets and C14 inlet included

The twelve IEC 60320 C13 receptacles allow direct connection of standard server and network power cords without additional adapters. The single C14 inlet connects to the primary supply while a second inlet on the rear accepts the redundant source. No configuration software or management modules are bundled with the unit.

Questions about this item

How do I install the AP4421A in a standard server rack, and what step is often missed?

Mount the unit in the rack, connect the C14 input to the primary source, then attach the secondary feed to the second inlet before wiring the 12 C13 outlets to your equipment.

What maintenance or replacement will the AP4421A need over time?

The internal transfer relay is the only wear item; plan to replace the module after its rated switching cycles or if the self-test indicates degraded contact resistance.

What limit appears first when the AP4421A runs at full load continuously?

The 10 A input rating is the first constraint; total connected draw across all 12 C13 outlets must stay at or below 10 A at 230 V to avoid tripping the internal breaker.
