7SJ8041-5EB96-3FB0 L0D SIEMENS

The 7SJ8041-5EB96-3FB0 L0D is a comprehensive overcurrent protection relay from Siemens, designed for advanced power system management. Housed in a compact 1/6 19" rack-mountable case, it features versatile mounting options, including flush mounting, and utilizes screw-type terminals for secure connections. This relay supports a wide range of auxiliary voltages, accommodating DC (60V/110V/125V/220V) and AC (115V/230V) power supplies. It is equipped with multiple current and voltage inputs (4 x I, 3 x U) alongside 7 binary inputs and 8 binary outputs (with 2 changeover contacts) and a live status contact. Communication capabilities are extensive, including a standard front system port, a rear MODBUS port (RS485), and an Ethernet interface (RJ45) for DIGSI configuration (not IEC61850). The relay offers comprehensive metering functions, such as fault recording and average/min/max value tracking. Protection functionalities include time overcurrent protection for phase and ground faults, overload protection, trip circuit supervision, and negative sequence protection. Additional features encompass directional ground fault protection, voltage and frequency protection, flexible protection functions, and undercurrent monitoring, with lockout functionality, but excludes auto-reclosure and fault location capabilities.
