Constant Torque Characteristic
– The left graph below shows the effect of the constant
torque characteristic curve. For example, at 2.5Hz, the output current level to cause overheating
in a fixed time period is reduced by a factor of 0.9. The right graph below shows the reduced
trip current levels in those conditions 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.
The left graph below shows the region for possible free-setting curves. The right graph below
shows an example curve defined by three data points specified by B015 – B020.
