                         Three-phase motor                                                                      single phase motor 

 

Three-phase  motors  have  a  rated  voltage

,  AT  50Hz,  of  230VΔ/400VY,  and  they  can  accept  a  ±

  10%  line 

voltage variation, according to IEC 38 specification. 

The same line voltage variation is allowed for single-phase motors with a rated voltage of 230V at 50Hz. 

According to IEC 34 specification a ± 5% line voltage is allowed for motors with any other rated voltage at 
50Hz and for any voltage at 60Hz. 

 

All SC blower and exhauster are equipped with a KLIXON thermal protector. (See attached specification), 
which must be connected to the main terminal box. Warranty will be void in case of either misconnection 
or wrong connection of the KLIXON.
