The many features of the 269Plus make it an ideal choice for a wide range of motor protection applications.
Versatile features and controls allow the relay to protect associated mechanical equipment as well as the
motor. The 269Plus should be considered for the following and other typical uses:
1. Protection of motors and equipment from operator abuse.
2. Protection of personnel from shock hazards due to winding shorts or earth leakage current from moisture.
3. Protection of gears, pumps, fans, saw mills, cutters, and compressors from mechanical jam.
4. Protection for loss of suction for pumps or loss of air flow for fans using the undercurrent feature.
5. Protection of motor and load bearings from excessive heat buildup due to mechanical wear.
6. Protection of motors operated in environments with varying ambient temperatures.
7. Communication with programmable controllers and computers for integrated plant control.
8. Protection of high inertia, long acceleration drive systems using a custom overload curve.
9. Statistical record-keeping for effective maintenance programs.
10. Complete protection, allowing maximum motor utilization with minimum downtime, for all AC motors.
