side mounting.
To reduce the risk of an inter-phase short circuit due to overvoltage, we recommend connecting a 3TX7 462-3L type
2)
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.
