Ordering Information

Budgetary Price:
$2,900 

The SEL-632 is designed for specific applications. For ordering information related to your application, please contact your SEL sales representative.

The SEL-632 Network Protector Relay is compatible with many Westinghouse®-style network protectors and offers directional power protection for underground secondary and spot networks. The easy-to-install relay offers various trip and close modes along with RMS metering and oscillographic event reporting. The SEL-632 provides reliable service even in harsh environments with an operating temperature range of –40° to +125°C and submersibility to 25 feet.

  • Easy Installation
    Install easily with plug-in interface. The SEL-632 Relay is a great alternative to the electromechanical master and phasing relays found in many Westinghouse-style network protectors.
  • RMS Metering 

    Measure three-phase network voltage, current, difference voltage, and relay temperature to monitor system performance.

  • Built for Harsh Environments 

    Maintain high reliability, even in harsh environments, with an ambient temperature range of –40° to +125°C, submersibility to 25 feet, and a rugged chassis design.

  • Communications 

    Easily send and receive settings as well as retrieve event information with the optical interface port.

  • Front-Panel Display 

    View real-time relay status and metering with the high-visibility, four-character display. Two LEDs give immediate indication when the relay trip or close outputs are closed.

  • Event Reporting 

    Simplify root cause analysis with the 64-cycle event report, sampled at 256 samples per cycle, including voltage, current, and digital relay quantities.

  • Monitor power flow to a secondary network.
  • Prevent reverse power flow from a secondary network.
