Siemens 4AM6442-5AT10-0FA0 SITAS 1-Phase Transformer 2kVA

The Siemens 4AM6442-5AT10-0FA0 is a SITAS single-phase transformer designed for industrial control and isolation duties. It has a rated apparent power of 2 kVA, a 400 V ±5% primary voltage, and a 230 V secondary voltage, making it a practical fit for applications where a stable 230 V output is needed from a 400 V supply. Siemens identifies this model as both a control transformer and an isolation transformer, with screw and flat-type connections and screw mounting. That makes it a good fit for panel builders, OEMs, and maintenance teams that need a genuine Siemens transformer with clear technical data and known standards coverage.
