REF601 CE446BB1NH ABB feeder protection and measurement device,as a dedicated feeder protection and measurement device,aims to protect and control public utilities and industrial power systems in the primary and secondary distribution networks.REF601 as a protective measurement and control device is ABB Relion®Members of the 605 product series within the product family.

Compared to its peers,this device has excellent performance and availability,providing an excellent configuration that integrates protection,monitoring,and control functions.

The REF601 CE446BB1NH ABB feeder protection and measurement device provides main protection for overhead lines and cable feeders in distribution and secondary distribution networks.In addition,the surge stabilization function allows the device to be used as the main protection for distribution transformers.

As an alternative to conventional current transformers,this type of device comes with a Rogowski current sensor version,which helps reduce the volume of medium voltage switchgear,improve performance,and make it more standardized.

REF601 supports MODBUS RTU and IEC 60870-5-103 communication through two wire RS485.

Universal power supply 24-265 V AC/DC

Compression fit installation is simple and fast

Detachable terminal blocks with CT short-circuit facilities

On site optional MODBUS RTU,IEC60870-5-103 protocol

Main advantages

Compact and flexible

Easy to operate and use

Quick debugging through selective testing of protection functions,secondary signals,and communication functions

Capable of self-monitoring

The device is connected to traditional measurement sensors and can be used in confined spaces of compact medium voltage switchgear

application area

The REF601 CE446BB1NH ABB feeder protection and measurement device is widely used in the field of feeder protection and monitoring in power systems,suitable for various scales and types of power systems.
