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, IEC cable/line thermal, vector shift, sensitive earth fault (SEF), load encroachment, and frequency elements. Select the 5-inch, 800 × 480 color touchscreen display option to directly set, monitor, and control your system. Easily upgrade protection without cutting or drilling existing cutouts, given the relay’s small form factor and multiple mounting adapters. Quickly integrate the SEL-751 into serial- or Ethernet-based communications with IEC 61850 Edition 2, IEC 60870-5-103, the IEC 62439 Parallel Redundancy Protocol (PRP), Mirrored Bits communications, DeviceNet, Modbus, DNP3, and other protocols.
