ABB REF630 UBFNAAABBBAZANBBXB Feeder Protection and Device

ABB REF630   UBFNAAABBBAZANBBXB  Feeder Protection and Device

Overview

REM630 is a comprehensive motor management relay for protection, control,

measuring and supervision of medium and large synchronous and asynchronous

motors in medium voltage industrial power systems. REM630 is a member of ABB’s

Relion® product family and a part of its 630 series characterized by functional

scalability and flexible configurability. REM630 also features necessary control

functions required for the management of industrial motor feeder bays. The protection

relay can be used with both circuit-breaker controlled and contactor controlled drives.

The supported communication protocols including IEC 61850 offer seamless

connectivity to industrial automation systems.

Product variants

The IED capabilities can be adjusted by selecting a product variant. The IED

capabilities can be extended by adding HW and/or SW options to the basic variant. For

example, the physical communication connector can be either an electrical or optical

Ethernet connector.

The number of binary inputs and outputs depends on the amount of the optional BIO

modules selected. For a 4U IED, it is possible to take 2 additional BIO modules at the

maximum, and for a 6U IED, it is possible to take 4 additional BIO modules at the

maximum.

• Basic variant: 14 binary inputs and 9 binary outputs

• With one optional BIO module: 23 binary inputs and 18 binary outputs

• With two optional BIO modules: 32 binary inputs and 27 binary outputs

• With three optional BIO modules: 41 binary inputs and 36 binary outputs

• With four optional BIO modules: 50 binary inputs and 45 binary outputs

Optional functions

Some of the available functions are optional, that is, they are included in the delivered

product only when defined by the order code.

• Frequency protection

• Overfrequency protection

• Underfrequency protection

• Frequency gradient

• Phase sequence voltage functions

Positive-sequence overvoltage protection

• Positive-sequence undervoltage protection

• Negative-sequence overvoltage protection

• Stabilized differential protection for motors

• Additional functions for synchronous motor

• Reverse power/directional overpower protection

• Three-phase underexcitation protection

• Rotor E/F protection

Physical hardware

The mechanical design of the IED is based on a robust mechanical rack. The HW

design is based on the possibility to adapt the HW module configuration to different

customer applications.
