The 269PLUS-DO-212-10C-120 is a motor protection system relay created by GE Multilin as part of the 269 Plus Motor Protection System family. The system is designed for three-phase motors. It provides protection against thermal and electrical damage to such motors. Specific events that the system protects against include stator windings and bearing overtemperature, multiple motor starts, undercurrents of load loss, locked rotors, fast tripping/mechanical clogging, unbalanced/single phase, short circuits, and ground faults. The system includes many key features, including emergency start function, pre-trip alarm warning, 2 auxiliary relays, current and heat capacity metering, data logging, voltage and power metering, and various inputs and outputs. Inputs and outputs include 12 resistance thermal detectors (RTDS), 5 factory-programmed digital inputs, 4 output relays, and 1 programmable analog output. The system contains 10 ohms of copper rtd. These sensors have a display accuracy error of 2°C.

The system has a package size of 16 x 11 x 17 inches and a total weight of 8.6 pounds (3.9 kg). The incision required to install the front panel is approximately 6.85 inches wide and 10.875 inches high. Four 0.218 inch diameter mounting holes are placed at the corners of the panel. The hole spacing is 10.45 inches vertically and 6.125 inches horizontally. The operating environment of the device should be kept between -25 ° C and 60 ° C. The humidity should be kept below 95% without condensation.
