Frequently Asked Questions
-
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. -
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. -
Is phase unbalance measured using negative-sequence components?
Yes, it uses negative-sequence current calculations to detect unbalance and asymmetry. -
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. -
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. -
Does the REM610B11HCHR support start supervision logic?
Yes, it monitors start duration and frequency, ensuring the motor does not exceed thermal limits. -
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. -
Can the user configure protection logic using Boolean equations?
Yes, internal logic can be programmed using the graphical logic editor in PCM600 software. -
What is the sampling rate for the internal disturbance recorder?
The disturbance recorder samples at 32 samples per cycle, offering detailed waveform capture. -
