Product Introduction
ABB REM615 HBMCAEAGNDC1BBN11G is a motor protection and control IED built on ABB’s Relion 615 platform. It is intended for medium-voltage asynchronous motors in industrial drives, compressors, pumps, and process equipment where both protection selectivity and controlled start/stop logic are required.
The device integrates thermal modeling, locked-rotor detection, phase imbalance supervision, and breaker control logic in a single withdrawable unit architecture. Depending on configuration, it supports IEC 61850 station bus communication or IEC 60870-5-103 legacy integration, enabling deployment in both modern and retrofit substations.
Field deployment typically focuses on motor reliability in continuous process environments, where improper protection coordination directly results in mechanical stress, overheating, or unplanned downtime.
Frequently Asked Questions
Q: Can REM615 HBMCAEAGNDC1BBN11G be hot-swapped?
A: No. The 615 series is a withdrawable unit, but CT circuits must be shorted before removal. Removing under load risks CT open-circuit voltage and equipment damage.
Q: Is this relay still supported?
A: Yes. The 615 platform is still actively maintained in ABB’s installed base lifecycle program, including firmware support and PCM600 engineering tool compatibility.
Q: Will I lose settings during replacement?
A: Yes unless backed up. In field practice, settings must be exported via PCM600 and validated against the exact order code. Do not assume compatibility between similar REM615 variants.
Q: What is the most critical commissioning risk?
A: Motor parameter mismatch. Incorrect full-load current, start time, or thermal curve setup leads to nuisance trips or delayed protection under stall conditions.
