FAQ

1. Can REM610B11HCHR provide thermal overload protection using both IEC and ANSI curves?

   Yes, it allows selection between IEC and ANSI overload curves, tailored for motor protection under various load profiles.

2. Does the relay detect and trip on locked rotor conditions during start and running?

   Absolutely. It offers separate locked rotor detection for startup and for stalled conditions during motor operation.

3. Is phase unbalance measured using negative-sequence components?

   Yes, it uses negative-sequence current calculations to detect unbalance and asymmetry.

4. How are time delays configured for protection elements?

   Time delays can be configured individually for each protection stage through PCM600 or directly via the local HMI.

5. Can the REM610B11HCHR interface with SCADA systems?

   Yes, using Modbus RTU, IEC 60870-5-103, or optional IEC 61850, it integrates seamlessly with SCADA platforms.

6. Does the REM610B11HCHR support start supervision logic?

   Yes, it monitors start duration and frequency, ensuring the motor does not exceed thermal limits.

7. How does REM610B11HCHR differentiate between inrush current and short circuits?

   It uses time-current curve discrimination and optional inrush blocking logic to avoid nuisance tripping.

8. Can the user configure protection logic using Boolean equations?

   Yes, internal logic can be programmed using the graphical logic editor in PCM600 software.

9. What is the sampling rate for the internal disturbance recorder?

   The disturbance recorder samples at 32 samples per cycle, offering detailed waveform capture.

10. Can the relay operate in environments with high electromagnetic interference?

    Yes, it meets rigorous IEC standards for EMC immunity and is designed for high-interference industrial areas.
