Technical Data and Specifications
IEC Contactors and Starters
AC Ratings—AC-6A Operation
AC Ratings—AC-6B Operation
AC Ratings—AC-1 Operation
Notes
1
Example—The transformer has a nominal current of 10A with an inrush current of 18 times the nominal current. So, the contactor must have an
AC-3 current of 18/6 x 10A = 30A. Using an XTCE032C (32A AC-3) contactor is recommended.
2
Up to 690V.
