Application Fields
The REF615 is mainly used in the following scenarios:
Industrial Distribution: Protection for factory incoming feeders and comprehensive protection for motor circuits.
Commercial Buildings: Protection for critical distribution circuits in data centers and hospitals.
Utilities: Protection for 10kV outgoing feeders in substations and connection of distributed energy resources.
Installation and Maintenance
Installation Key Points
Use shielded wires of ≥2.5mm² for CT secondary wiring to avoid induced voltage interference.
Lay communication cables (e.g., Ethernet cables) and power cables in separate layers, with a spacing of ≥30cm.
Maintenance Recommendations
Conduct protection setting verification once a year (using a relay protection tester).
Regularly back up configuration parameters (via the PCM600 software).
