Rated frequency

50/60 Hz

Type of current

• Three-phase (grounded without decoupling module DCM, otherwise with decoupling module DCM)
• 1-phase AC (with decoupling module DCM)

Short-circuit protection

Additional short-circuit protection is required in the main circuit

Current measuring accuracy

Within the measuring range ± 3%

Typical voltage measuring range

• Phase-to-phase/line-to-ground voltage

110 V to 690 V (only the phase voltages are available to the system as measured values)

• Phase voltage

65 to 400 V

Voltage measuring accuracy in the range from 230 V to 400 V

Typically ± 3%

Voltage measurement in ungrounded systems or in systems with integrated insulation measurement or insulation monitoring

The current measuring module IM or the current/voltage measuring module UM can only be used in these systems in conjunction with a decoupling module DCM.

Supply lines for voltage measurement

Additional protection may need to be provided in the supply lines for voltage measurement.
