ABB REM610 Digital feeder protection relay
ABB REM610 is a digital feeder protection relay belonging to the ABB Relion series, designed for protection, control and monitoring of feeders in medium and low voltage distribution networks. The device integrates multiple protection functions, which can quickly detect and isolate faults such as short circuit, overload, grounding, overvoltage and undervoltage of feeders. It also has real-time measurement, event recording and communication functions to ensure the safe and stable operation of the distribution network. Its design meets industrial standards and can be directly installed in distribution switchgear or control cabinets.
