① the Characteristic of Inverse-time, the stronger of the current, The shorter of trip response time)
② Percent of rated input voltage ( i.e if the rated input voltage is 380V, the Over voltage trip is 437V, the Under voltage trip is 323V)
③ Percent of load time of calibration ( i.e if the running ampere of pump motor is 10A during the calibration, the dry running trip ampere is 7A)
④ Percent of load time of calibration ( i.e if the running ampere of pump motor is 10A during the calibration, The pump stalled trip ampere is 20A)
