Siemens 7SJ6475-2EB92-3FE0 SIPROTEC 7SJ64 Protection Relay Unit

Feature & Principle

This numerical protection relay collects current and voltage signals from CT and PT. It executes multi-stage overcurrent, earth fault, overload and unbalance protection logic, with built-in CFC programmable logic, fault recording and event logging. It supports IEC60870-5-103, Modbus communication, can connect RTD sensors for winding temperature monitoring, and outputs trip signal once fault is detected.
