EK550, EK1000 4-pole contactors

800 to 1000 A AC-1
AC operated with 1 N.O. + 1 N.C. auxiliary contacts

EK550 4-pole contactors are mainly used for controlling non-inductive or slightly inductive loads
(i.e. resistance furnaces...) and generally for controlling power circuits up to 1000 V AC and
03
600 V DC, EK1000 up to 1000 V AC.
These contactors are of the block type design with:
• 4 main poles
1SFC98099-069 • control circuit: AC operated
• add-on auxiliary contact blocks for side mounting and a wide range of accessories.
