The ABB REF542plus 1VCF752000 is a feeder terminal unit belonging to the ABB Ability™ Relion® 650 series, specifically designed for protection, control, and monitoring of feeders, transformers, and motors in medium and low-voltage power distribution systems.

 It integrates a comprehensive range of protection functions, including overcurrent protection, earth fault protection, directional protection, voltage protection, frequency protection, 

and thermal overload protection, enabling rapid and reliable response to feeder faults such as overcurrent, earth faults, and short circuits. In terms of control capabilities, 

it supports circuit breaker control, disconnector control, automatic reclosing, and closing supervision, facilitating both local and remote operation of feeder switchgear by operators. Additionally,

 it provides real-time monitoring of electrical parameters like current, voltage, 

power, frequency, and energy, along with event recording and fault waveform recording features to support fault analysis and system maintenance. 

Compatible with multiple communication protocols including IEC 60870-5-103, optional IEC 61850, and optional Modbus RTU/TCP, the unit can be easily integrated into automation systems for remote monitoring and control. 

It operates within a supply voltage range of AC/DC 24-250V, withstands an operating temperature range of -25°C to +70°C, and supports both panel mounting and DIN rail mounting. 

Widely applied in power distribution networks for industry, commerce, and utilities (such as factories, mines, petrochemical facilities, large commercial complexes, hospitals, and schools),

 it is also suitable for renewable energy grid connection and rail transit power supply scenarios.
