The electrical study for the implementation of a CleanWave

®

 filter is very easy.  The few instructions 

described in this document must however be respected in order to ensure the safety and efficiency 
of the system.

In order to minimise the disturbing currents in the installation, the CleanWave

®

 filter should be 

placed close to the disturbing load. 
 
 

 
The CleanWave

®

 filter must be protected in a similar way as a transformer. 

 
 As a standard rule, the electrical protection D1 must be a tetrapolar circuit breaker ( 3 phases + 
neutral ) with neutral over-current detection. 
 
If such a protection is not possible (e.g. when the neutral and earth connectors are common (PEN)), 
a tripolar breaker will be used and the PEN conductor section will be doubled, as recommended 
in table 4. 
 
The breakers must be selected according to the phase current as given in table 4 here above.  The 
maximum inrush current is lower or equal to the nominal current and doesn't require particular 
precautions. 
  

 
The minimum recommended wiring sections for the different connectors are given in table 4.  These 
are minimum recommendations according to the European regulations. Higher sections may be 
used according to local regulations, particularities of the electrical installation or specific rules. 
 
The  neutral conductor may be crossed by a current up to 1.8 times the phase current and is 
therefore over-sized.
