Phase asymmetry:

Phase asymmetry is present in a 3-phase network when one phase is overloaded compared to the others. The APMR detects even a "creeping" asymmetry, which is usually not detected by thermal and magnetic devices.

Phase failure:

In the event of a phase failure, the contact to a phase is completely interrupted. The APMR detects a phase failure even in the event of voltage feedback.

Incorrect phase sequence:

If the phase sequence is incorrect, two of the three phases are reversed. This causes a motor to reverse its direction of rotation, for example. The APMR detects an incorrect phase sequence regardless of the load on the individual phases.

Undervoltage:

The APMR detects an undervoltage on the phases. A delay time can be set to avoid a switching relay when the motor starts up.
