AF1250 ... AF2850 3-pole contactors
475 to 560 kW and 1260 to 2850 A AC-1
AC / DC operated with 1 N.O. + 1 N.C. auxiliary contacts

AF1250 ... AF2050 contactors are mainly used for controlling power circuits up to 1000 V AC or 03
850 V DC, AF2650 and AF2850 for controlling power up to 1000 V AC. These contactors are of the
block type design with 3 main poles.
– control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage
range
(e.g. 100...250 V AC and DC)
- only 4 coils for AF1250 to cover control voltages between 48...500 V 50/60 Hz and 24...500 V DC
- only 1 coil for AF1350 ... AF2850 to cover control voltages between 100...250 V 50/60 Hz and
100...250 V DC
- can manage large control voltage variations
1SFC101027V0001 - reduced panel energy consumption
- very distinct closing and opening
- can withstand short voltage dips and voltages sags (SEMI F47 conditions of use on request).
• built-in surge suppression
AF1250-30-11
• add-on auxiliary contact blocks for side mounting and a wide range of accessories.

(1) The connection polarities indicated close to the coil terminals must be respected: A1 for the positive pole and A2 for the negative
pole.(2) AF2650: Maximum operational voltage = 1000 V according to UL / CSA.
AF1250 ... AF2850 are equipped with low voltage inputs for control, for example by a PLC
