Description
The zigzag connection is meant for loads that generate many harmonics. Power depends on the K-factor and the winding material. For K4 it is 10–630 kVA with copper and 40–2000 kVA with aluminum, while for K20 it is 7–450 kVA with copper and 28–1400 kVA with aluminum. The DZN0 K20 A IP21 version has an aluminum winding. Insulation is class H with a temperature rise of 125 K, and the core is M270 steel. The design follows EN 60076 and IEC 61558, with IP00 or IP21 enclosure.
How to choose
First determine the K-factor of the load, 4, 13 or 20, because it sets the power range. Then pick the winding material, copper or aluminum, and the enclosure, IP00 or IP21. If a delta/star Dyn11 connection is required, look at DYN11 for 400/400 V, 50 Hz, which reaches 1000 kVA with copper for K4.

FAQ
Which loads is the DZN0 transformer designed for?
For loads with a high harmonic content, including UPS and BESS. The Dzn0 zigzag connection is intended for exactly that duty.
Which K-factors does DZN0 come in?
4, 13 and 20. The K-factor sets the power range, for example K20 covers 7–450 kVA with a copper winding.
Does DZN0 have a copper or an aluminum winding?
Both options exist. For K4 that is 10–630 kVA with copper (Cu) and 40–2000 kVA with aluminum (Al).
What insulation class and standards apply to DZN0?
Class H with a temperature rise of 125 K and an M270 steel core. Standards are EN 60076 and IEC 61558.
Which enclosure ratings are available for DZN0?
IP00 or IP21. The DZN0 K20 A IP21 version has an aluminum winding.
