Description

This calibrated current transformer is mostly used in equipment installation where the current circuit must be interrupted. It embodies the most compact design currently available on the market and is therefore suitable for installation in the control cabinet. This calibrated current transformer is suitable for accounting purposes and its design approved by the "Physikalisch Technische Bundesanstalt" (PTB) in Braunschweig. The possibility of attaching the converter to the primary conductor and thus avoiding the complex wiring is to be particularly highlighted. In addition to control cabinet construction, mechanical engineering and plant construction are further areas of application of the clip-on current transformer
