Product Description

REM610C11HCNR02 product is a motor protection relay, the following is a detailed description of its products:

Product Overview:
The REM610C11HCNR02 is a member of the ABB Relion product family and belongs to the 610 product family.
Designed for medium and large standard asynchronous motor protection, it is widely used in a variety of medium voltage motor equipment.
Main functional features:
Motor protection: Protect motors in a variety of motor applications, such as pumps, blowers, grinders or crusher applications.
Three-phase protection: Provides three-phase overcurrent protection, three-phase short-circuit protection, three-phase undercurrent (loss of load) protection, etc., with timing characteristics and speed switch blocking function.
Thermal overload protection: three-phase motor startup monitoring based on thermal stress calculation to prevent motor overheating.
Unbalanced and reversed phase protection: three-phase unbalanced protection based on negative phase sequence current, with inverse fixed minimum time characteristics, and reversed phase protection based on negative phase sequence current.
Temperature and fault protection: Temperature protection level with timing characteristics, and circuit breaker fault protection.
Cumulative start and Emergency start: A cumulative start time counter with restart suppression, and emergency start.
Human Machine interface and Communication:
The liquid crystal display (LCD) provides intuitive operation instructions and LED lights show the status of power failure.
Supports local control of relays through serial communication from computers connected to front-end communication ports.
An optional rear communication module supports system communication using the SPA bus, IEC 60870-5-103 or Modbus (RTU and ASCII) communication protocols.
Input and output:
With six measurement inputs, support for PTC thermistors and various RTD sensors.
Three normally open power output contacts, two conversion signal output contacts, the output contact function can be freely configured according to needs.
Interference loggers can record up to 100 time-stamped event codes, as well as recording four analog channels and up to eight user-optional digital channels.
Other features:
User optional rated frequency 50/60 Hz.
Support multi-language HMI, user can choose password protection for HMI.
All Settings can be modified from the PC.
Application field:
It is mainly used for the protection, measurement and monitoring of small and medium-sized asynchronous low voltage motors and small and medium-sized asynchronous high voltage motors in the manufacturing and processing industries.
