g GE Power Management 269Plus Motor Management Relay

g GE Power Management 269Plus Motor Management Relay Offering optimum motor protection in situations where other relays cannot, the 269 Plus Motor Management Relay possesses the unique feature of its ability to “learn” individual motor parameters, giving it the flexibility to adapt to each application by “learning” values of motor inrush current, negative sequence current K factor, cool down rates, start thermal capacity and acceleration time.
