REF601

Description

series
The REF601 is a member of the ABB Relion® product family and belongs to the 605 series.
trait
Protection and control: The REF601 combines protection, monitoring and control functions with three-stage overcurrent and two-stage ground fault protection.
Inrush current stabilization function: It can prevent unnecessary tripping caused by transformer energizing.
Preconfiguration and flexibility: It is possible to preconfigure and quickly debug switchgear by setting specific application parameters within the intended application range of the relay.
Communication protocols: Support MODBUS RTU and IEC 60870-5-103 communication protocols.
Multiple application configurations: Provides different application configurations to meet different protection requirements, such as non-directional overcurrent and ground fault protection, thermal overload protection, and negative phase sequence protection.
Input/Output configuration: With four standard binary inputs and six output contacts, it can be configured for various functions, such as protective start/trip signal routing, external trip/tripping, etc.

effect
Feeder protection: REF601 is used as a feeder protection relay to protect utility substations and industrial power systems in primary and secondary distribution networks.
Short circuit and overcurrent protection: Provides protection against short circuit, overcurrent and ground faults for overhead lines and cable feeders in distribution and secondary distribution networks.
Transformer protection: Relays with surge current stabilization function can be used as the main protection device for distribution transformers.
