    - Phase failure
    - Phase sequence

Impervious to harmonics up to a distortion factor of K 20 %
Fallback delay adjustable from 0.1 → 5 s
One LED indicator for each of the following: auxiliary voltage A1 / A2; overvoltage U_MAX; undervoltage U_MIN; asymmetry / phase sequence / mains failure; contact position
One device for networks with and without a neutral conductor
Rest current principle
2 changeovers
Overall width 45 mm
