The lightweight SEL-351RS Kestrel Single-Phase Recloser Control provides integrated logic, communications, and comprehensive protection for single-phase applications. Convenient operator controls allow easy local access to metering and event data. The rugged, low-maintenance, painted aluminum enclosure reduces the need for cabinet maintenance and repairs. With built-in USB serial and Ethernet media and protocols, including IEC 61850 and IEEE C37.118 synchrophasors, you can easily integrate this control into new or existing communications systems.

Applications

Protection—Protect single-phase distribution circuits with comprehensive protection capabilities, including time-overcurrent, autoreclosing, over-/undervoltage, frequency, and more. Increase service restoration efficiency with accurate fault location.

EZ Settings—Commission the SEL-351RS Kestrel Single-Phase Recloser Control into systems quickly using EZ settings. EZ settings are similar to traditional recloser control settings.

Inrush Detection—Detect transformer energization or motor startup and block tripping until inrush conditions subside using the second-harmonic blocking element.

Flexible Communications—Coordinate relay-to-relay operation with high-speed Mirrored Bits communications. Integrate into serial and Ethernet communications networks with standard DNP3 or Modbus protocols or the optional IEC 61850 protocol.

System Monitoring—View system and recloser conditions using the integrated web server.
