Popular Model

Complete Motor Protection—Protect medium-voltage induction motors, regardless of horsepower rating. Apply the integrated thermal protection model to retain “learned” motor thermal characteristics through transitional operating states (start, run, stop, restart).

Event Reports and Trends—Confirm motor sizing, understand events, and satisfy information requirements of supervisory systems with the SEL-701 Relay’s comprehensive reporting. Reports such as motor starts, Sequential Events Recorder (SER), and full event reports provide unprecedented analytical tools for motor applications and load profiling. Reports are retained in nonvolatile memory.

Programmable RTDs—Select each RTD type and location, and then include RTD inputs as part of the integrated thermal model to bias protection. Field-configurable RTDs accommodate a variety of RTD types and locations.

Simple Communication—Interface with the relay using the EIA-232 or EIA-485 serial communications port, which supports ASCII communication using popular terminal emulation communications programs. Use Microsoft Windows-based acSELerator QuickSet SEL-5030 Software to create, modify, send, receive, and save SEL-701 settings.


Complete Motor Protection
Integrated thermal protection model (patented). Flexible protection for induction and synchronous motors.

Event Reports and Trends
Comprehensive event reports stored in nonvolatile memory: motor starts, motor start trend, load profile, SER, and full event reports.

Programmable RTDs
Field-configurable RTDs from local front-panel or communications 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.
