Line Harmonics Filters are supplied as stand-alone components in a rugged housing. They are installed between the customer's low-voltage distribution panel and the converter. The voltage is disconnected and fused in the customer's low-voltage switchgear, as is the power supply cable.

The Line Harmonics Filters have no fans (natural convection cooling). This means that no external auxiliary power supply is required.

The Line Harmonics Filters are equipped with a floating thermostatic switch, which can be monitored externally, for the monitoring thermal overloads, e.g. as a result of insufficient cooling air being supplied.

Note:

The converter must have a line reactor in order to use a Line Harmonics Filter.
