Key Features and Benefits
The ABB REF610 offers diverse protection functions, including three-phase overcurrent protection (with low, high, and instantaneous settings), non-directional grounding fault protection (with low and high settings), phase discontinuity protection, three-phase cable thermal overload protection, and circuit breaker failure protection. It also provides arc protection when equipped with optional hardware. Its advanced protection algorithms ensure fast and accurate fault detection and isolation, minimizing damage to equipment and reducing power outage durations. The REF610 features multiple time-current characteristics, including nine inverse definite minimum time (IDMT) curves. Users can select the appropriate characteristic curve based on system requirements, enabling precise coordination of protection settings.
