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 220V, the Over voltage trip is

253V, the Under voltage trip is 187V)

③ Percent of load time of calibration ( i.e if the running ampere of pump motor is 6A during the

calibration, the dry running trip ampere is 4.2A)

④ Percent of load time of calibration ( i.e if the running ampere of pump motor is 6A during the calibration, The pump stalled trip ampere is 12A)
