The XJ11 Siemens Phase Failure and Phase Sequence Voltage Relay is a protective device used to monitor three-phase power supply conditions. It detects phase failure, wrong phase sequence, overvoltage, and undervoltage to protect electrical equipment. The relay ensures safe operation by disconnecting the system during power faults. Compact and reliable, it is suitable for industrial and commercial applications. This relay helps prevent motor damage, equipment failure, and electrical accidents.
