ABB introduces two new 615 series protection and control IEDs, REM615 and RET615. Re-engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 substation communication standard. The 615 series consists of protection and control IEDs designed for the protection, control, measurement and supervision of network equipment in utility and industry power distribution networks. The IEDs are characterized by their compactness and withdrawable design. The 615 series is a part of ABB’s Relion® product family.

RED615 provides phase-segregated high speed, longitudinal differential protection for overhead line and cable feeders in distribution networks. REM615 constitutes main protection for asynchronous motors and their drives in manufacturing and process industry. RET615 is the ultimate differential protection and control IED for two-winding power transformers and power generator-transformer blocks. REF615 provides main protection for overhead lines, cable feeders and busbar systems of distribution substations.
