| Notes | For the version with enhanced climatic proofing the transformer features a special insulating varnish. This version enables the transformer to be used in areas with a high humidity. When ordering, the type reference must include the following details: ETSP25(*/*)1st wildcard ≙ Nominal input voltage 2nd wildcard ≙ Rated output voltage Ordering example
SN = S x (1 - Lower voltage ⁄ Higher voltage) = 55 kVA x (1 - 230V/400V = 23.4 kVA SN = kVA type rating S = Throughput rating
The correct type reference is ETSP25(400/230) Transformer-protective circuit-breaker ￫ 088907 |
