1)
The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are
attenuated against voltage peaks (suppression diode 6x to 10x; diode combinations 2x to 6x; varistor +2 to 5 ms).
2)
Acc. to IEC 60947-4-1. See the chapter titled "Overload relays" for rated values for different starting conditions.
3)
The data specified is valid for 3RT2516 and 3RT2517 (2 NO contacts + 2 NC contacts) only up to a rated operational
current of 400 V.
4)
The number of lamps can be increased dependent upon the electronic ballast used.
