Siemens 7SJ8081-5EB90-3FC1-L0S Overcurrent Protection Relay
Siemens 7SJ8081-5EB90-3FC1-L0S Overcurrent Protection Relay
The Siemens 7SJ8081-5EB90-3FC1-L0S is a versatile overcurrent protection relay housed in a 1/6 19" unit. It offers extensive input/output capabilities, including 4 current inputs, 3 voltage inputs, 11 binary inputs, and 5 binary outputs (2 changeover). It supports a wide range of auxiliary voltages, both DC (60V, 110V, 125V, 220V) and AC (115V, 230V), and features a screw-type terminal connection. The device is designed for flush-mounting and comes with English language support, which is changeable.
This protection relay is equipped with IEC 61850 communication via 100MBIT Ethernet with an integrated switch and LC connectors. Its functionality includes phase overcurrent protection (50/51), ground fault protection (50N/51N, IEE>, IEE>>, IEEP), overload protection (49), trip circuit supervision (74TC), and breaker failure protection. Additional features like directional phase & ground overcurrent, sensitive ground fault voltage, and frequency protection are also included, along with flexible protection functions and automatic reclosing capabilities.
