Complete integrated protection and management of medium and large motors The Multilin™ 469 Motor Protection System, a member of the SR family of relays, provides protection, control, simplified configuration and advanced communications in a cost effective industry leading draw-out construction. Designed for medium voltage motors, the 469 delivers advanced protection with customizable overload curves and single CT differential protection for added flexibility. The 469 also provides simplified configuration using the Motor Settings Auto-Configurator, providing a quick and easy set-up of motor parameters. Coupled with advanced protection and diagnostics, the 469 provides users the flexibility of multiple communication protocols allowing integration into new and existing control networks. Key Benefits • Comprehensive motor protection plus voltage dependant overload curves, torque metering and protection, broken rotor bar protection • Most advanced thermal model - Including multiple RTD inputs for stator thermal protection • Minimize replacement time - Draw-out construction • Complete asset monitoring - Temperature, Analog I/O, full metering including demand & energy • Improve uptime of auxiliary equipment - Through I/O monitoring • Reduce troubleshooting time and maintenance costs - Event reports, waveform capture, data logger • Built in simulation functions simplify testing and commissioning • Cost Effective Access to information - Through standard RS232 & RS485 serial ports, and optional Ethernet and DeviceNet Ports • Field upgradable firmware and settings • Optional Conformal coating for exposure to chemically corrosive or humid environments Applications • Protection and Management of three phase medium and large horsepower motors and driven equipment, including high inertia, two speed and reduced-voltage start motors
