Line contactors

Line contactors are required to provide electrical isolation between the drive line-up and the
line supply.
When selecting a line contactor, the characteristic values in the technical data apply. The
cable routing, the bundling factor and the factor for the ambient temperature according to
EN 60204-1 must be taken into account when dimensioning the various cables.
Caution
Line contactors must not be switched under load.
When the digital output is used to control the line contactor, its making/breaking capacity
must be taken into account.
