Siemens AG 61-300-053-506 Current Transformer steps down high primary currents for isolated, accurate measurement by converting them to a 0.5 A secondary through a 800:0.5 CT ratio. This CT is intended for connection to metering, protection relays, and instrumentation that require a safe, scaled representation of AC current, enabling precise monitoring without exposing measurement circuits to live power. Identified by the part number 61-300-053-506, it integrates into Siemens-based electrical systems and other compatible installations that rely on a precise current transformer for monitoring and protection tasks.
