REQ650 ABB Breaker Protection Relay

Product Description

The ABB REQ650 is identified in the supplied information as a breaker protection relay for monitoring electrical conditions and supporting circuit-breaker protection functions. The listed specifications include AC/DC input voltage options, 1 A or 5 A current inputs, relay output contacts, and communication interfaces. Confirm the exact hardware configuration and supported protocols before selecting the unit for an existing protection system.

Key Functions

The REQ650 provides configurable protection and control functions for circuit-breaker applications. Its current and voltage measurement inputs supply electrical quantities for protection logic, while output contacts can transmit trip, alarm, or control signals according to the configured application.

Communication capabilities depend on the installed hardware and configured protocol. Verify the required interface and protocol against the relay's exact ordering code before connecting it to a substation automation or monitoring system.

Technical Specifications

Configuration Considerations

• Current inputs: Match the relay's rated current inputs to the installed current transformers and the configured protection settings.
• Power supply: Confirm the auxiliary supply rating from the relay nameplate and hardware configuration before energizing the unit.
• Communication: Confirm the required protocol, Ethernet interface, and any optional communication modules before integration.
• Protection settings: Verify the enabled protection functions and configured logic against the application requirements before commissioning.

Frequently Asked Questions

Q: Does the ABB REQ650 support IEC 61850 communication?

A: IEC 61850 communication is supported by the REQ650 product family. Confirm the installed communication hardware and protocol configuration for the specific unit.

Q: Can the REQ650 accept 1 A and 5 A current inputs?

A: The product documentation identifies 1 A and 5 A rated current input options. Confirm the installed input configuration and match it to the current transformer secondary rating.

Q: Are all REQ650 units configured with the same communication interfaces?

A: No. Available interfaces and protocols can vary with the hardware configuration and ordering options. Check the complete ordering code before selecting a replacement relay.
