EK550, EK1000 4-pole contactors

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

Description
EK550 4-pole contactors are mainly used for controlling non-inductive or slightly inductive loads (i.e. resist-
ance furnaces...) and generally for controlling power circuits up to 1000 V AC and 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.
