1)
The 3RT2916-1GA00 additional load module is recommended for higher
residual currents,
see page 3/118
.
2)
The OFF-delay of the NO contact and the ON-delay of the NC contact
are increased if the contactor coils are attenuated against voltage peaks
(noise suppression diode 6 to 10 times; diode assembly 2 to 6 times,
suppressor diode +1 ms to 5 ms; varistor +2 ms to 5 ms).
