400 V (data given on the unit nameplate).
*** Maximum unit operating current at maximum unit power input and 360 V.
**** Maximum unit operating current at maximum unit power input and 400 V (values given on the unit nameplate).
Maximum instantaneous start-up current at operating limit values (maximum operating current of the smallest compressor(s) + fan current + locked rotor current of the
largest compressor).
Fan motor electrical data: current used in the tables below:
Units at Eurovent conditions and motor ambient air temperature of 50°C at 400 V:
3.8 A, start-up current 20 A, power input 1.75 kW.
These values are those given on the motor nameplate.

Icw: assigned short-time current
*** Ipk: assigned current, admissible peak
For units with options 12 and 116 use the higher value.
†† Icc/Icf: assigned conditional short-circuit current
IT system:
The short circuit current stability values given above for the TN system are also valid for IT for units 30RB 302 to 522. For units 30RB 162 to 262 and 30RB 602 to 802
modifications are required.
