SR469-CASE|Traditional motor protection system
The SR469 motor protection system is part of the SR relay family and offers protection, control, simplified configuration and advanced communication features in a cost-effective, industry-leading pull-out construction. Designed for medium voltage motors, the 469 offers advanced protection with customizable overload curves and single CT differential protection for increased flexibility. The 469 also provides simplified configuration using the motor Setup autoconfigurator, providing quick and easy motor parameter Settings. Combined with advanced protection and diagnostic capabilities, the 469 provides users with the flexibility of multiple communication protocols, allowing integration into new and existing control networks.
Major advantage
Voltage dependent overload curve, torque measurement and protection, rotor bar break protection
State-of-the-art thermal model - multiple RTD inputs for stator thermal protection
Minimizes replacement time - withdrawable construction
Complete asset monitoring - temperature, analog I/O, full metering
Improve the uptime of auxiliary devices - through I/O monitoring
Reduce troubleshooting time and maintenance costs - event reporting, waveform capture, data loggers
Built-in simulation simplifies testing and debugging
Cost-effective access to information - via standard RS232 and RS485 serial ports, as well as optional Ethernet and DeviceNet ports
Firmware and Settings can be updated on site
