Siemens 7SJ6325-5EB92-3FG0 Protection Relay

Feature & Principle

It is Siemens SIPROTEC 7SJ63 multifunctional overcurrent protection relay. It collects three-phase current and voltage signals, judges fault conditions according to protection setting values, and quickly sends trip signal to circuit breaker when overcurrent, earth fault or overload occurs. It has built-in measurement, fault recording and event logging functions, supports DIGSI software parameter configuration. Profibus-DP interface realizes data interaction with upper monitoring system. It is widely used for distribution feeder, motor and transformer backup protection in substation.
