Product positioning and family background: REF615 belongs to ABB Relion ® The 615 series is an intelligent electronic device (IED) specifically designed for public substations and industrial power systems. This series is characterized by compact design and withdrawable units. The REF615 undertakes important tasks of protection, control, measurement, and monitoring, and is widely applicable to various distribution networks, including radial, ring, and mesh networks with or without distributed generation.
Output connections: Output connections are divided into trip and control outputs, signal outputs, and IRF (internal fault relay) outputs. The tripping and control output are achieved through PO1-PO4 contacts, which can control most circuit breakers; The signal output is transmitted through SO1-SO4 contacts to indicate the starting and tripping status of the equipment; IRF contacts have different closed states under normal and fault conditions, used for self-monitoring systems of equipment.
