Core application areas
REF610 as Relief ® The 610 series feeder protection relay is mainly used in the following scenarios:
Distribution station incoming and outgoing line protection: covering the incoming and outgoing circuits of public and industrial distribution systems, providing core protection such as overcurrent and grounding faults.
Equipment backup protection: As a backup protection for motors, transformers, and generators, it supplements the main protection function and improves system reliability.
Special Environmental Adaptation: Suitable for harsh environments such as ships and offshore platforms, meeting industrial grade requirements for anti vibration and temperature resistance.
Arc protection extension: Combined with optional fiber optic sensors, it enables rapid detection and isolation of arc faults in switchgear, busbars, and cable terminals.
