GE 369-HI-R-0-0-E-0-E Motor Management Relay
Performance characteristics
Rich protection functions: It is equipped with multiple protection functions such as under-voltage automatic restart,
reverse power, starter failure, kVA demand, kvar demand, kW demand, current demand, rotary detection, and
mechanical blockage. It can also monitor and protect against stator RTD, voltage reverse phase, current imbalance,
bearing RTD, under-current/under-power and other conditions, effectively ensuring the safe operation of the motor.
Prevent motor damage caused by various faults.
Flexible input configuration: The "R" in the model indicates that it is equipped with 12 built-in resistance temperature
detector (RTD) inputs, which can be used to monitor parameters such as bearing, stator and ambient temperature,
helping users understand the temperature status of the motor in real time and providing an important basis for motor
maintenance and fault diagnosis.
The control power supply range is wide: The control power supply is 50-300VDC or 60-264VAC, which can adapt to
various different power supply environments and is easy to integrate into various different systems, meeting the
application requirements in different industrial scenarios.
The communication interface is optional: It is equipped with a Modbus/TCP protocol interface (indicated by "E" in the
model), which facilitates communication and connection with other devices or systems. It can transmit relay-related
data to the monitoring system to achieve remote monitoring and management, allowing users to grasp the motor
operation status in real time and improve operation and maintenance efficiency.
Powerful diagnostic function: It features enhanced diagnostic capabilities, providing detailed motor health reports,
motor start-up records, and other information. It is also equipped with an advanced event recorder, which helps users
quickly identify the cause of faults, conduct troubleshooting and preventive maintenance, and reduce motor downtime.
User-friendly operation interface: It adopts an upgraded front panel design, providing a user-friendly interface for
convenient configuration and monitoring operations. Users can program set points on-site, access alarm and trip
information through the display, and also have status indicator lights and help keys, making operation very convenient.
Superior contact performance: As an electromagnetic relay, it has a large contact capacity and can withstand a large
current load. It is suitable for controlling the start, stop and direction of motors and other operations. It has a long
mechanical and electrical life. After multiple engagement and release, it can still maintain a normal working state and
can work continuously for a long time, with high durability.
Strong environmental adaptability: It has a high protection level, excellent dust-proof, moisture-proof and shock-proof
performance, and can adapt to relatively harsh working environments. Meanwhile, it is small in size, light in weight,
and has strong anti-interference ability, making it suitable for various industrial automation equipment that requires
motor control.
Application field
Power industry: It can be used for the protection and control of various types of motors in power plants, such as
auxiliary motors of generators and motors in plant power systems, ensuring the stable operation of motors in complex
power environments and preventing power generation interruptions or equipment damage caused by electrical faults.
Meanwhile, in substations, it can also be used to protect motors such as cooling fans and oil pumps, ensuring the
normal operation and heat dissipation requirements of substation equipment.
In the petrochemical industry, there are a large number of motor-driven equipment in the petrochemical production
process, such as reactor stirring motors, oil pipeline pump motors, compressor motors, etc. This relay can provide
comprehensive protection for these motors, preventing safety accidents caused by faults such as overcurrent and
overheating of the motors, and ensuring the continuity and safety of petrochemical production.
In the metallurgical industry, in metallurgical production processes such as blast furnace ironmaking and converter
steelmaking, there are numerous large motors used to drive equipment like blowers, steel rolling mills, and cranes. The
369-HI-R-0-0-E-0-E motor protection relay can adapt to the harsh working environment of high temperature and high
dust in the metallurgical industry, effectively protect the motor, reduce equipment failure downtime, and improve
production efficiency.
In the field of mine hoisting: It can be used for the protection of the motor of the mine hoist. The mine hoist is one of
the important equipment in the mine, responsible for hoisting ores, personnel and materials, etc. The relay can
monitor the operating status of the elevator motor in real time and act promptly when a fault occurs, ensuring the
safety and reliability of the lifting process.
In the port field, equipment such as cranes, belt conveyors and ship unloaders in ports all rely on electric motors for
driving. This relay can protect and monitor these motors, ensuring the smooth progress of port loading and unloading
operations and enhancing the port's cargo handling capacity and operational efficiency.
Water treatment industry: In water treatment plants, it is used for the protection of pump motors, such as raw water
pumps, clean water pumps, sewage pumps, etc. It can ensure the normal operation of the water pump, guarantee the
stability of the water treatment process, and provide reliable support for urban water supply and sewage treatment.
In the papermaking industry, during the papermaking process, all the transmission parts of the paper machine as well
as auxiliary equipment such as fans and water pumps require motor drive. This relay can effectively protect these
motors, prevent motor failures from affecting the production quality and output of paper, and ensure the stable
operation of the papermaking production line.
Textile industry: It can be applied to motor protection in textile machinery, such as motors in spinning machines,
weaving machines, printing and dyeing equipment, etc. It helps to reduce the impact of motor failures on textile
production, improve the quality and production efficiency of textiles, and lower maintenance costs.
In the heating and water supply industry: In the heating system, it can protect the motors of circulating water pumps,
make-up water pumps, etc., ensuring stable heating. In the water supply system, it can ensure the normal operation of
motors such as water source water intake pumps and water plant booster pumps, providing stable water supply
services for residents and enterprises.
