It is REM543 and higher I/O variant is REM545. This
numerical protection relay is used for protection of
rotating electrical machines either induction motor or
synchronous machine (Both motor and generator). REM54x is
freely programmable relay and functions and logic can be
programmed using CAP505 tool.

SPAJ is a series of SPACOM family relay working on current
inputs and communicating on SPA protocol. This family of
relays is designed for various feeder prortection
applications and not for motors
