Measures and weights

 

CONNECTIONS BETWEEN PHASES:

  • Single input voltage between 100V and 500V
  • Single output voltage between 100V and 110V

(For other tensions, please consult).

PHASE-TO-EARTH CONNECTION:

  • Single input voltage between 100V/ √3 and 500V/ √3
  • Single output voltage between 100V/ √3 and 110V/ √3

(For other tensions, please consult).
