ABB REJ601 BD446NN1XG Product Introduction

Product model:

REJ601 BD446NN1XG(model needs to be bolded,using Markdown syntax)

Main features and advantages:

REJ601 BD446NN1XG is ABB Relion®The overcurrent protection relay in the 605 series is designed specifically for medium voltage distribution systems,focusing on overcurrent and ground fault protection for feeders,cables,and transformers.Its core advantages include:

High reliability and compactness:Adopting a 1/2 rack width design,with a small installation depth,supporting press in installation,suitable for compact switchgear and space limited scenarios.

Multi level protection function:Integrated three-level overcurrent protection(including timed DT and inverse time IDMT characteristics)and two-level grounding fault protection,supporting IEC and ANSI standards,compatible with different power grid requirements.

Intelligent monitoring and diagnosis:Built in surge current detection function to prevent accidental tripping of transformers during charging;Provide 100 event records with timestamps for easy fault tracing.

Flexible communication and configuration:Supports Modbus RTU and IEC 60870-5-103 communication protocols,and can set parameters through local HMI or remote interface to adapt to various automation systems.

Environmental adaptability:Universal power input(24-250V AC/DC),wide temperature operation(-25°C to 70°C),anti electromagnetic interference design,suitable for harsh industrial environments.
