SEL-751A SPECIAL-1754 FEEDER PROTECTION RELAY 751A01D1D3D72810310

SEL recommends selecting the SEL-751 Feeder Protection Relay in place of the SEL-751A. The SEL-751 supports additional protection and communications options, such as fault location, high-impedance fault detection, EtherNet/IP, and an integrated web server. It is also available with a color touchscreen display.

Comprehensive Protection and Fast Response

The SEL-751A SPECIAL-1754 covers multiple protection functions, including overcurrent, earth fault, breaker failure, and sensitive earth fault. The relay's microprocessor-based technology allows for operation in less than 15 milliseconds, minimizing system disruptions and damage during faults. Its event memory and trip circuit supervision further enhance system diagnostics and reliability for critical feeder applications.


Flexible Integration and Communication

Designed for modern substations, the SEL-751A supports Ethernet, Serial, and USB ports and is compatible with leading protocols, including IEC 61850, DNP3, Modbus, and SEL Protocol. This ensures seamless connectivity with various SCADA and automation systems, making integration straightforward for operators and engineers.


Durable Construction for Demanding Environments

With an enclosure rating of IP52 (front) and IP20 (rear), as well as a wide ambient temperature range (-40C to +85C), the relay provides protection and reliability in harsh industrial settings. The device complies with IEC 60255 and IEEE standards, and its 10-million-operation mechanical life promises longevity even under demanding operational cycles.
