SEL recommends selecting the SEL-710-5 Motor Protection Relay or the SEL-849 Motor Management Relay in place of the SEL-701. The SEL-710-5 protects a full range of medium-voltage, three-phase induction and synchronous motors and is available with a color touchscreen display. The SEL-849 protects low- or medium-voltage three-phase induction and variable-frequency drive-fed motors and can be easily installed inside a motor control center.
SEL will continue to support and warranty the SEL-701.
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.
