Siemens 6GK5534-3TR00-3AR3 SCALANCE XR522-12 Layer 3 Switch, 230V AC, 8x SFP+ 10G

The Siemens SCALANCE XR522-12 (6GK5534-3TR00-3AR3) is a 19-inch rack, Layer 3 managed Ethernet switch with 20x 10/100/1000 Mbit/s RJ45 ports, 2x combo 1G/2.5G/5G/10G RJ45 ports, 4x SFP ports, and 8x SFP+ ports for 10 Gbit/s uplinks. It runs from a single 100-240V AC/DC-rated supply on an IEC C14 inlet and integrates a redundancy manager for ring topologies.

Selection Notes

The 3AR3 variant takes a single AC mains feed on an IEC C14 inlet (the same terminal also accepts 100-250V DC) - the option to pick when the panel has mains AC available and a second supply isn't required. Pick the 2AR3 sibling for a 24V DC bus instead, or 4AR3 for a factory-fitted redundant pair. Against the larger XR526-8, the XR522-12 trades 4 RJ45 ports for 4 extra SFP slots, which suits sites standardizing on fiber for part of the access layer.

Applications

The mixed RJ45/SFP/SFP+ port set fits distribution cabinets that combine copper drops to local PROFINET devices with fiber runs to remote panels, using MRP or HSR/PRP for ring redundancy across the plant backbone.
