GE SR469 Series Motor Management Relay
GE SR469 series motor management relay
The SR469 motor protection system is a member of the SR series relays, providing protection, control, simplified
configuration and advanced communication in a cost-effective, industry-leading extended structure. Designed
specifically for medium-voltage motors, the 469 offers advanced protection, with customizable overload curves and
single CT differential protection, enhancing flexibility. The 469 also uses a motor setting auto-configurator to provide
simplified configuration, offering quick and easy motor parameter Settings. Coupled with advanced protection and
diagnosis, 469 provides users with the flexibility of multiple communication protocols, allowing for integration into
new and existing control networks.
Characteristics
Voltage-related overload curve, torque measurement and protection, rotor broken bar protection
The most advanced thermal model - multiple RTD input stator thermal protection
Minimize replacement time - pull-out construction
Complete asset monitoring - temperature, analog I/O, full measurement
Improve the uptime of auxiliary equipment - through I/O monitoring
Reduce troubleshooting time and maintenance costs - event reporting, waveform capture, data logger
The built-in simulation function simplifies testing and debugging
Access information economically and effectively - via standard RS232 and RS485 serial ports, as well as optional
Ethernet and DeviceNet ports
Firmware and Settings can be upgraded on-site
Optional conformal coating exposure
Multilin™F650 is designed for the protection, control and automation of feeders or related applications. The Multilin
F650 provides high-speed protection and control for feeder management and channel control applications, and is
equipped with a large LCD and a single-line diagram. It can be used for channel monitoring and control in various
feeder arrangements, including ring busbars, double circuit breakers or double circuit breakers and half circuit breakers.
The design features advanced communication options and detailed monitoring functions. The Multilin f650 offers
advanced functions, including high-performance protection, extensive control functions and flexible configuration
functions. The Multilin F650 can also be used in various applications instead of feeder protection and control.
Main advantages
Comprehensive and flexible protection and control devices suitable for feeder applications
Increase the system's uptime and improve stability through load reduction and transfer schemes
Advanced automation functions for customizing protection and control solutions
The human-machine interface (HMI) is equipped with a graphic LCD, programmable buttons, and simple keys for
selecting Settings menus and submenus
Reduce replacement time through a modular withdrawable structure
Reduce troubleshooting time and maintenance costs through IEEE 1588 (PTP), IRIG-B and SNTP time synchronization
(configuring two different SNTP master stations), event reporting, waveform capture and data logger
Simplify system integration by supporting serial and Ethernet interfaces as well as multiple protocol communications
• Embedded IEC® 61850 protocol (and supports Version 2), IEC 60870-5-103/104, IEC 62439/PRP/HSR,
IEEE 802.1D/RSTP
