Contactor Relays
SIRIUS 3RH2 contactor relays, 4- and 8-pole

1)
The additional load module 3RT2916-1GA00 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
(suppression diode 6x to 10x; diode assembly 2x to 6x;
varistor +2 to 5 ms).
