ABB REM610 Motor Protection Relay

Product Introduction

The ABB REM610 is a dedicated motor protection relay designed to provide comprehensive protection, supervision, and control for asynchronous (induction) motors in industrial, utility, and infrastructure applications. As a member of the Relion® 610 series, the REM610 is built on proven technology that ensures dependable motor operation, efficient energy use, and system reliability.

This relay supports low- and medium-voltage motors and offers reliable protection against thermal overload, phase failures, locked rotor, unbalance, and short circuits. It integrates seamlessly with various control and monitoring systems, offering flexible installation options and robust communication capabilities through widely accepted industrial protocols.

Frequently Asked Questions

1. Can the REM610 perform thermal overload protection based on IEC curves?
   Yes, the relay provides thermal overload protection using configurable IEC or ANSI curves to match motor characteristics.

2. Does the REM610 detect locked rotor conditions during startup?
   Yes, it includes locked rotor detection using time-current characteristics during motor start-up.

3. How does the REM610 differentiate between motor start-up inrush and actual faults?
   It uses a built-in start-up supervision logic with configurable time delays to ignore normal inrush currents.

4. Can REM610 monitor motor start time and number of starts?
   Yes, it tracks cumulative start times and restricts the number of starts per hour to prevent overheating.

5. Is phase reversal detection available?
   Yes, the relay can detect incorrect phase sequence and block motor start accordingly.

6. Can I use REM610 with both 1 A and 5 A CTs?
   Yes, it supports selectable current inputs via configuration for both 1 A and 5 A CTs.

7. Is the REM610 suitable for motors started via soft starters or VFDs?
   Yes, it can be used with DOL, soft starters, or VFDs, though protections must be adjusted accordingly.

8. Can REM610 interface with a SCADA system using IEC 61850?
   Yes, some models support IEC 61850 for full SCADA and substation automation integration.

9. What fault records does REM610 store?
   It stores up to 16 fault records including fault type, duration, current values, and time stamps.

10. Does the relay support event tagging with real-time clock?
    Yes, events and faults are time-stamped using the relay’s internal clock, which can be synchronized via communication protocols.
