EK550, EK1000 4-pole Contactors

800 to 1000 A AC-1
AC operated with 2 N.O. + 2 N.C. auxiliary contacts

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