- Enhanced Monitoring
Seven user-programmable LED targets for enhanced monitoring flexibility.
- Full Motor Protection Functionality
Full motor protection functionality to maximize product value and utilization.
- Thermal Model Control
User control of the thermal element to simplify monitoring functions when thermal element is not in use.
- Programmable RTDs
Individually programmable RTDs, each with one trip and three alarm levels, for enhanced thermal monitoring and control of critical substation apparatus.
- Event Reports and Trends
Comprehensive event reports stored in nonvolatile memory: motor starts, motor start trend, load profile, Sequential Events Recorder (SER), and full event reports.
- Simple Communication
ASCII and Modbus® communication 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 or other power system apparatus).

- Monitor thermal characteristics of transformers and alarm for adverse internal or ambient conditions.
- Program and label front-panel LEDs to reflect monitored conditions such as thermal alarms, cooling fan status, contact input states, or calculated SELOGIC® control equations results of other measured conditions.
- Monitor intake and exhaust air temperatures in a critical motor while alarming for rising ambient temperatures in the switch yard.
- 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 SEL-5010 Relay Assistant Software to manage your relay settings.
