Siemens 7SJ6216-5EB92-1 Protection Relay

Feature & Principle

It is Siemens SIPROTEC 7SJ62 series numerical protection relay. It samples current and voltage signals continuously, executes overcurrent, earth fault, overload and phase unbalance protection algorithms. It can send trip command to circuit breaker when fault occurs, meanwhile record fault event and oscillography data. It supports Modbus, IEC60870-5-103 communication for connecting to SCADA system, with local HMI for parameter setting and status checking.
