Siemens Sirius Electronic Overcurrent Relay 1No+1Nc 50-200A Size S6 3RB2056-1FC2 Overcurrent relays combine reverse and independent time relays in a single device. These relays are used to protect transformers, motors, generators and power transmission lines in the power distribution system against short circuits and ground faults. "Selective protection" should be applied to ensure the highest level of protection. The main purpose of selective protection is to limit the fault to the minimum and disconnect the connection as soon as possible.
