Product Overview

The Siemens 4AM5742-8DD40-0FA0 is a single-phase control and isolation transformer from the SITAS family (Siemens brand SIDAC), designed for industrial control systems requiring stepped-down secondary voltages for control circuits and protective relays. It delivers 1 kVA continuous apparent power with 5 kVA short-term vector capability. It supports a wide range of primary voltages and provides dual secondary outputs. Typical use cases include control panel power feeding, isolation for signal circuits, and transformer-based control of protection devices.
