1)
The reduced values in brackets apply in the case of a directly mounted motor starter protector combined with side-by-
side mounting.
2)
To reduce the risk of an inter-phase short circuit due to overvoltage, we recommend connecting a 3TX7 462-3L type
varistor between phases L1 and L3, as close as possible to the switching device. We recommend a design with
semiconductor protection to provide short-circuit protection.
