  • Rated voltage: U = 3 x 500 V
  • Insulation material class: T40/B
  • Protection: Variants of IP00 up to IP66 possible
  • Climartic category: DIN IEC 60068-1
  • Overload: 1,5 x INenn 1 min / h


Technical Data


  • Nominal Voltage : 500 V
  • Rated current : 6 - 70 A
  • Inductance : 0,42 - 4,88 mH
