ABB REF610 Feeder Protection Relay Product Detailed Explanation
Product Overview
ABB REF610 is a powerful and widely used feeder protection relay, mainly used to protect the feeders of the distribution system. It can quickly and accurately detect and protect various faults on the feeder, such as short circuit, ground fault, overload, etc., to ensure the reliable supply of electric energy.

Main Functions
Overcurrent Protection: Detect and protect the feeder from damage by overcurrent.
Ground Fault Protection: Detect and protect the feeder from the influence of ground fault.
Directional Overcurrent Protection: Distinguish the fault direction and improve the selectivity.
Undervoltage Protection: Cut off the load when the voltage is too low to protect the equipment.
Overvoltage Protection: Cut off the load when the voltage is too high to protect the equipment.
Zero Sequence Current Protection: Detect ground fault and improve the protection sensitivity.

Product Features
