Type
Size
Main circuit - Current carrying capacity for alternating current
Utilization category AC-6a, switching AC transformers
Rated operational current I

- For inrush current
n = 20
- For inrush current
n = 30
Rated power P

- For inrush current
n = 20
- For inrush current
n = 30
For deviating inrush current factors x, the power must be recalculated as follows: P
The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are
1)
attenuated against voltage peaks (suppression diode 6x to 10x; diode combinations 2x to 6x; varistor +2 to 5 ms).
Acc. to IEC 60947-4-1. See the chapter titled "Overload relays" for rated values for different starting conditions.
2)
The data specified is valid for 3RT2516 and 3RT2517 (2 NO contacts + 2 NC contacts) only up to a rated operational
3)
current of 400 V.
The number of lamps can be increased dependent upon the electronic ballast used.
