The table below shows the settings and their meanings. Use the one that matches your load.
Reduced Torque Characteristic – The example below shows the effect of the reduced torque
characteristic curve (for example motor and current rating). At 20Hz, the output current is
reduced by a factor of 0.8 for given trip times.
Constant Torque Characteristic – Selecting the constant torque characteristic for the example
motor gives the curves below. At 2.5 Hz, the output current is reduced by a factor of 0.9 for
given trip times.
Free Thermal Characteristic - It is possible to set the electronic thermal characteristic using a
free-form curve defined by three data points, according to the table below.
