Arcing time
Dependency of switching frequency z'on operational current I' and
operational voltage U'
z' = z ⋅ I /I' ⋅ (U /U')1.5 ⋅ 1/h

The use of the additional load module 3RT2916-1GA00 is recommended at higher residual currents.
1)
The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are
2)
attenuated against voltage peaks (suppression diode 6x to 10x; diode combination 2x to 6x; varistor +2 to 5 ms).
