3.2.2 Connection of contactors
Use spark suppression, for larger contactors also interface relays to keep good lifetime of the UMC22
internal relays.
Actual ABB contactors - all currents for 230 V AC (Extract)
1)
The contactor B6S-30-10-2.8 (24 V DC) is recommended as interface contactor due to its internal
spark suppression.
2)
All values only for contactors with spark suppression, see appropriate column. Use interface contactor
if higher lifetime is required.
3)
Interface contactor is recommended (e.g. B6S-30-10-2.8).
4)
The contactors for higher currents are available with electronic interface only
5)
Also available with electronic interface (AF50 to AF185).
Remark:
Spark suppression is necessary for all types except the AF types to keep resonable lifetime.
