UMG 605US
Three-phase 4-wire systems
The UMG605US can be used in three-phase
4 conductor systems (TN, TT system) (50 Hz,
60 Hz) with earthed PEN conductor. The
bodies of the electrical system are earthed.
The conductor to neutral conductor voltage
may not exceed 300 V AC.
The UMG605US is only suitable for
environments in which the impulse voltage
withstand level of 4 kV (overvoltage category
III) is not exceeded.
