The 169PLUS-100P-240 is a member of the GE Multilin 169 Plus series of motor management relays. This specific relay and other 169 or 169 Plus Multilin relays have a variety of end applications for the user.  These relays can be used to protect a variety of motors and their corresponding mechanical equipment due to the versatility of the features included in the relay. For example, the 169PLUS-100P-240 can be used to protect a motor from shock hazards in the event of a winding short or an earth leakage current due to moisture conditions. This 169 Plus relay can also be used to protect components of the motor from a mechanical jam (saw mills, compressors, pumps, gears, fans, etc.). The relay is able to connect to computers and other programmable controllers to enhance communication ability within the plant as a whole. A custom overload curve is used to protect drive systems with longer acceleration than normal or in situations when drives experience high inertia conditions. The provided undercurrent feature provides protection of motors in the event of lost pump suction or loss of fan airflow.  These protection features described above are simply a brief summary of the variable protection that a 169 Multilin motor management relay provides the user. An increase in tailored protection is seen with the 169 Plus Multilin models, which affords the user additional features for customizable protection and management of motors.
