It handles 25 A per phase, with an inductance of 1.170 mH and a short-circuit voltage of 4% at 400 VAC, helping limit fault currents and shape supply impedance. The unit weighs 3.80 kg and uses screw-clamp terminals for 10 mm² conductors, with DIN rail mounting and M4 fixing screws; insulation class IEC F (UL class 155), IP 00, and a 2500 VAC insulation test. The operating ambient range is −10 °C to +40 °C, and the model is listed as discontinued for new designs by BLOCK.\u003c\/p\u003e\u003c\/div\u003e","brand":"Block","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677099163950,"sku":null,"price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_24c3877b-3a4b-44dd-9846-e2bffd8babda.jpg?v=1769557761","url":"https:\/\/plgautomation.com\/products\/block-nkd-25-1-17-un-400v-60hz-power-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
