Yes, this solid state overload relay calculates ground fault condition based on a summation of the three phase current. It is adjustable from 0.15 times minimum over current setting to 0.20 times the maximum over current setting. Please note that the device is for equipment protection and in no way should be used as people protection. Additionally, this solid state overload is not intended to take the place of branch circuit protective devices, such as circuit breakers or fuses.
