Description

The REF620 is a dedicated feeder IED perfectly aligned for the

protection, control, measurement and supervision of utility substations and industrial power systems.

REF620 is a member of ABB’s Relion® family and a part of its

620 protection and control product series. 

The 620 series IEDs are characterized by flexibility and performance for demanding

utility distribution and industrial applications.

Engineered from the ground up, the 620 series has been designed to unleash the

full potential of the IEC 61850 standard for communication and

interoperability of substation automation devices.

The REF620 NBFNAAAAABC1BNN1XF, part of the ABB Relion 620 family,

is a versatile digital protection device for the protection and control of power systems.

Here are some of the key features and parameters of the product:

Versatility: The REF620 provides integrated protection, measurement, control, 

and monitoring capabilities for a variety of voltage levels and network topologies.

Communication capabilities: Support for IEC 61850 standards, 

including GOOSE and SV communications, enabling interoperability of smart substations.

Advanced protection functions: including differential protection, overcurrent protection, ground protection, 

overtemperature protection and other protection functions.

Advanced measurement features: Provide highly accurate current, voltage, power and energy measurements.

Unique REF620 ANSI features

− Six setting groups

− Drawout design

− Underground, overhead cable fault detection (CFD)

− High-speed (< 1 ms) outputs

− High impedance (HIZ) fault detection

− Arc flash detection (AFD)

− Phase step distance protection

The REF620 provides main protection for overhead lines,cable feeders, and busbar systems of distribution substations.

It can be applied for protection and control of grounded and ungrounded distribution systems. 

It offers support for single breaker, one-and-half breaker and double breaker feeder configurations.

Flexible order coding allows for choosing current-only

or current-and-voltage configurations to best fit your distribution feeder application needs.

APPLICATION

The REF543KM127AAAA is a feeder terminal produced by ABB that is used in a wide range of applications. 

Designed for protection, control, measurement and monitoring of medium voltage networks,

the device can be used with different types of switchgear, such as single bus, 

dual bus and dual machine systems, and supports a variety of network types, including isolated neutral networks,

resonant ground networks and partially grounded networks.

It is especially suitable for the protection and control of medium-sized three-phase asynchronous motors, 

as well as the protection and control of shunt capacitor banks for reactive power compensation. 

The REF543KM127AAAA unit integrates a variety of automation and sequential logic control functions that are critical to substation automation. 

In addition, it also has a variety of communication interfaces, support such as SPA bus, LON bus, 

IEC 60870-5-103 and other communication standards, enabling fast and interference-free data communication.

In industrial automation control systems, the REF543KM127AAAA comprehensive protection relay also plays an important role,

which is not only used to connect and control cables and wires, but also has a number of notable features, 

such as compact design, high reliability, and the ability to withstand voltages up to 1000V.

In addition, the REF543KM127AAAA feeder terminal unit module can be used in a variety of applications, 

including manufacturing, energy, chemical, construction, water treatment, etc., and is ideal for automated control and monitoring systems. 

It provides a high-performance processor, a variety of communication interfaces and built-in security features to ensure the efficient operation and security of the system
