IWF with busbar 20x5


CONSTRUCTION AND APPLICATION:

The IWF transformers are made as single-phase, low voltage, indoor, dry transformers on a ring core, intended to supply measuring instruments with the maximum permissible operating voltage below 0.72 kV and a frequency of 50 Hz. The IWF transformers are designed to be mounted on a current circuit bus through primary terminals of the 20x5* transformer. In addition, they can be installed on a TS 35 -35x7.5 mounting rail (as per EN 50022, BS 5584 or DIN 46277-3) or fixed to the ground via sleeve joints with Ø 5.4 openings, which are provided as part of the transformer delivery.

The transformer secondary current is 5A.

The Current Transformers meet the requirements of PN-EN 61869-1:2009  i PN-EN 61869-2:2013-06 European Standards.

ll current transformers manufactured by F.A.E. „FANINA” S.A. are calibrated by the company laboratory, and the calibration costs are included in the price of the product. Additionally, at the Client’s request, we provide current transformers calibrated by the Regional Weights and Measures Office orcalibratedby the accredited PCA laboratory (extra charge)
