Technical Parameters Parameter Category Description / Value Brand & Series Eaton, CI Series (Control Interface) for PKZ0 System Model Number CI-K2-PKZ0-GR Compatibility PKZ0 motor starter system Function K2 - Specific control function (e.g., specific relay configuration, interface type). Color GR - Gray Rated Operational Voltage (Ue) Dependent on internal relay/electronics (e.g., 24V DC, 230V AC). Contact Configuration Specific to the K2 function (e.g., may contain relays with NO/NC contacts). Mounting DIN Rail (35mm), typically mounts adjacent to or integrated with the PKZ0 starter. Standards Compliance Relevant parts of IEC/EN 60947 series (e.g., -4-1, -5-1).
