APC NetShelter Automatic Transfer Switch 30A 208V AP4431A

SKU CH-FEQ5-Z5JZW

Rack-mounted 2U automatic transfer switch provides redundant power for 30A 208V equipment with dual L6-30P inputs and single output

  • 30 A capacity supports high-density rack loads
  • 208 V input matches common three-phase distribution
  • Automatic transfer switches sources in milliseconds
  • Dual L6-30P inlets provide redundant power paths
  • 2U form factor fits standard rack enclosures

APC NetShelter ATS 30A 208V

The APC NetShelter Automatic Transfer Switch AP4431A provides redundant power for single-corded rack equipment. It accepts two 30A 208V feeds through L6-30P inputs and delivers one L6-30R output. The unit occupies 2U of rack space and includes mounting brackets and a serial configuration cable.

Suited for racks needing automatic failover

This switch suits environments where two independent 30A 208V sources are available and automatic transfer is required. It is not for installations limited to a single power feed, for loads exceeding 30A, for voltages other than 208V, or for racks that cannot accommodate a 2U device.

Dual L6-30P inputs with single L6-30R output

The defining specification is the dual 30A 208V input configuration feeding one 30A 208V output. Both sources must match this voltage and connector type for the transfer function to operate correctly.

Highlights

  • 30 A capacity supports high-density rack loads
  • 208 V input matches common three-phase distribution
  • Automatic transfer switches sources in milliseconds
  • Dual L6-30P inlets provide redundant power paths
  • 2U form factor fits standard rack enclosures

Questions about this item

What rack mounting hardware does the AP4431A include for installation?

The switch ships with rack mounting brackets and mounting hardware so it can be secured directly into a standard rack.

Which cables must be connected to the two L6-30P inputs for the automatic transfer function to work?

Both L6-30P input plugs need to be fed from separate 30 A 208 V sources; the transfer switch will not operate if only one source is connected.

What ongoing checks are recommended for the automatic transfer switch to maintain reliable failover?

Periodically verify that both input sources remain live, inspect the power cords for damage, and test the transfer function by simulating a source loss.
