The REF543KB127AAAA is a feeder integrated protection device control relay manufactured by ABB. It is mainly used in public substations and industrial power systems to protect, control, measure and supervise overhead lines and cable feeders. Here are the details:
Protection function: With over current protection, quick break protection, overload protection and other protection functions, can quickly and accurately make protection actions for different fault types.
Control function: REF543KB127AAAA can realize the remote control of the medium voltage feeder, such as closing, opening and other operations, while monitoring and controlling the switching status in real time.
Measurement function: It can measure and display electrical parameters such as current and voltage in real time, providing accurate data reference for operators.
Monitoring function: REF543KB127AAAA monitors the medium voltage feeder in real time through internal sensors and measurement modules, detecting anomalies in time and triggering alarms to help prevent

  accidents.
Man-machine interface: equipped with large graphical display or external display module, convenient for operators to view data and monitor the status. Supports flexible switch cabinet installation methods and can be customized according to actual requirements.
Communication function: REF543KB127AAAA supports a variety of communication protocols, such as IEC61850, IEC60870-5-103 and Modbus®, etc., to facilitate data interaction and integration with other systems.
The device is suitable for a variety of medium voltage network application scenarios, including radial, ring and mesh distribution networks with or without distributed generation. At the same time, it can adapt to new application areas of smart grid development, such as power quality measurement, protection, capacitor bank protection and control, and motor protection.
