The phase protection has two separately adjustable settings:
- the low setting may be chosen with definite time or IDMT. The IDMTcurves are in compliance with the IEC255-3 standard. They are of the standard inverse, very inverse and extremely inverse types. The low setting may also be used with the RI curve.

measurement: it uses the sum of the sensor secondary currents. Like phase protection, earth protection has two separately adjustable settings.
