SEL-751

The SEL-751 is the ideal solution for utility feeder protection and industrial protection, with support for conventional/analog current and voltage inputs, flexible I/O options, easy mounting and quick setups.

The SEL-751 provides comprehensive protection for radial and loop distribution circuits. It offers arc flash mitigation, fault location, high impedance fault detection, broken conductor detection, event analysis, and more. You can quickly integrate the relay into serial or Ethernet-based communications with IEC 61850 Edition 2, IEC 60870-5-103, IEC 62439 Parallel Redundancy Protocol (PRP), EtherNet/IP, IEEE 1588 Precision Time Protocol (PTP), Modbus, DNP3, and other protocols.
