269Plus Motor Management Relay

The 269 Plus is a microprocessor based product designed to provide complete and accurate protection for industrial motors and their associated mechanical systems. The 269 Plus monitors the rotor and stator winding temperatures and shuts off the motor when thermal limits are exceeded.It also shuts down the motor when it detects a potentially damaging or hazardous condition. All RTD inputs not used for stator winding protection can have individual settings for temperature monitoring functions. This allows both motor and driven load bearings to be monitored by the relay.
