Overview
The Schneider Electric SEP888 Base Unit is the primary operator and communication interface for Sepam Series 80 protection relays. Designed for substation and industrial power system environments, it features a mimic-based User Machine Interface (UMI) that allows operators to easily visualize system status, acknowledge alarms, and interact with protection and control functions directly from the front panel.
Its wide operating voltage range (24–250 V AC/DC) and rugged construction ensure dependable performance in harsh electrical environments. Additionally, the SEP888 simplifies configuration and diagnostics, reducing commissioning time and improving operational efficiency. Therefore, it is widely used in switchgear panels, utility substations, and critical industrial power systems where fast response and system reliability are essential.
