SEL-701

Motor Protection Relay

The SEL-701 Relay provides complete induction motor protection combined with innovative monitoring, reporting, metering, and control capabilities.

SEL-701 Motor Protection Relay
CSA CE

  • Complete Motor Protection
    Integrated thermal protection model(patented). Flexible protection for induction and synchronous motors.
  • Event Reports and Trends
    Comprehensive event reports stored in non-volatile memory: motor starts, motor start trend, load profile, Sequential Events Records (SER), and full event reports.
  • Programmable RTDs
    Field-configurable RTDs from local front panel or communication port.
  • Simple Communication
    Modbus Communications along with ASCII/binary interface using off-the-shelf communications packages (terminal emulators).

  • Voltage inputs for complete metering and power information
  • Internal RTDs (11 RTD inputs for internal RTD card)
  • External RTDs (12 RTD inputs and one contact input on SEL-2600A RTD Module mounted near motor)
  • Conformal Coating—Protect equipment from harsh environments and airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.

  • Protect most medium voltage induction and synchronous motors regardless of horsepower rating.
  • Apply the integrated thermal protection model to retain motor thermal characteristics through transitional operating states (start, run, stop, restart).
  • Use comprehensive reporting to confirm motor sizing, understand events, schedule maintenance, detect unfavorable trends, modify loads, and satisfy information requirements of supervisory systems.
  • After selecting each RTD type and location, include RTD inputs as a part of the integrated thermal model to bias protection.
  • Select the external RTD module (SEL-2600A) to eliminate expensive wire pulls and reduce wiring terminations at the relay by as much as 40%, while acquiring clean RTD signals and an additional contact input.
  • Apply the SEL-701 Relay in unfavorable environmental conditions. Tested from -40° to +85°C and up to 95% relative humidity (non-condensing).
  • Select from among 45 standard motor protection curves, use nameplate data, or create specialized curves according to unique motor operating requirements.
  • Use ACSELERATOR® QuickSet™ SEL-5030 or SEL-5010 Relay Assistant Software to manage your relay settings.

SEL provides options to help you efficiently and safely commission and test these relays.
SEL-4391 Data Courier Streamline commissioning by using the SEL-4391 Data Courier™ to send and retrieve settings, gather event reports, and install enhancements.
