ABB REM615 Motor Protection Relay

Overview：

The REM615 is a dedicated motor protection device designed for the protection, control, measurement, and monitoring of asynchronous motors in manufacturing and processing industries. Typically, in drive applications, the REM615 is used in combination with high-voltage motors controlled by circuit breakers or contactors, as well as medium to large low-voltage motors controlled by contactors. The REM615 features four standard configurations, including all basic motor protection functions, voltage protection functions, and power and energy measurement. It also greatly facilitates local or remote start/stop control of motors.

Main Advantages:

• Integrates protection, control, measurement, and monitoring functions in one relay protection device
• Provides motor start, load loss monitoring, thermal overload, and motor reverse protection, and can use sensors or traditional CT/PT
• Pre-configured standard configurations and the ability to quickly and easily meet different application requirements through functional configuration
• Pluggable design for quick installation and testing
• Large LCD display with editable single-line diagram, accessible via local or web browser-based user-friendly HMI
• Comprehensive product lifecycle services

Main Features:

• Provides protection and measurement functions based on voltage and frequency
• Offers protection and fault clearing for abnormalities during motor start and operation
• Optional arc flash protection and high-speed output
• Supports IEC61850 Edition 1 and Edition 2, including redundant HSR and PRP, GOOSE, and IEC61850-9-2 LE
• Supports IEEE 1588 v2 high-precision time protocol
• Supports MODBUS, DNP3, and IEC 60870-5-103
