The Multilinm 469 Motor Protection System, a member of the SR family of relays, provides protectioncontrol, simplified configuration and advanced communications in a cost effective industry leadingdraw-out construction. Designed for medium voltage motors, the 469 delivers advanced protection withcustomizable overload curves and single CT differential protection for added flexibility. The 469 alsoprovides simplified configuration using the Motor Settings Auto-Configurator, providing a quick and easyset-up of motor parameters. Coupled with advanced protection and diagnostics, the 469 provides usersthe flexiblity of multiple communication protocols allowing integration into new and existing controlnetworks.
