Product Introduction
In medium-voltage switchgear upgrades, relay replacement problems usually come from configuration drift rather than failed hardware. ABB REF615E-D is a feeder protection and control relay used in utility substations, industrial power distribution systems, and ring main units where selective feeder protection and communication integration are required.
The unit supports IEC 61850 communication, programmable logic through PCM600, and withdrawable construction for faster maintenance access. Typical installations use 1 A or 5 A CT inputs with station communication through GOOSE or Modbus TCP. Before commissioning, verify firmware package compatibility, signal matrix configuration, and protection logic against the existing project file.
