Selected transformer STZ4,0(400/230), max. current: 25 A;
4000 VA: 230 V (:√3*) = 17,4 A < 25 A
No excess charge as the current is in the permissible range
Selected transformer STZ4,0(400/110), max. current: 25 A;
4000 VA: 110 V (:√3*) = 36,4 A > 25 A larger design necessary
Select from the table: larger design up to 63 A: type affix + STR25/63, excess charge 12,60 Euro
(*) for three-phase current
Technical notes
Excess charge for higher currents
larger dimensioned terminals for
STEZ, STEN, STENE, STZ, ET, ETSP, DTZ, DT, DTSP
When selecting a transformer, the input voltages, the output voltages and the requested output must be considered. The basic price of the selected transformer is always related to a specific current (refer to order indications, column `Price for current up to`). If, due to selected output and voltage, the actual current exceeds the output of the basic type, an excess charge will be added.
