ZB4-908-SF1 Eaton Overload Relay

The ZB4-908-SF1 is an overload relay equipped with an 8MB memory card. It supports data logging and configuration storage consistent with the functional requirements of industrial motor protection systems. The memory capacity is fixed at 8MB and is integrated into the device architecture. No additional memory expansion or external storage interfaces are specified. This unit operates within the defined parameters of its designated series and complies with applicable industrial control standards for overload relays. The memory card enables retention of operational history, trip records, and setup parameters without requiring continuous power supply to preserve stored data.
