The SEL-751 Feeder Protection Relay is ideal for directional overcurrent, fault location, arc-flash detection, and high-impedance fault detection applications. Flexible I/O options, easy mounting, and fast settings make the SEL-751 the right solution for industrial and utility feeder protection. The SEL-751 provides complete feeder protection, with overcurrent, overvoltage, undervoltage, directional power, load encroachment, and frequency elements. Easily upgrade protection without cutting or drilling existing cutouts, with a small form factor and multiple mounting adapters. Quickly integrate into serial- or Ethernet-based communications with IEC 61850, Mirrored Bits communications, DeviceNet, Modbus, DNP3, and other protocols.
