Eg. 3RT2045-1SB30 according to the catalog has a current 400V AC (AC-2 and AC-3) - 80A 690V AC (AC-1) - 125A But what current will be at 525V AC? Attachment 3RT2045.jpg (629 Downloads)

Unfortunately, there is no information for intermediate values like 525V. Best regards Sirius_3 Attachment IC10-2022.pdf (544 Downloads)
