Current transformer 1503206

Versatility & increased safety Moulded case current transformers are used if high currents are to be recorded and further processed. The line to be measured (conductor rail or wire) is fed through the window opening and forms the primary circuit for the plug-on current transformer. Moulded case current transformers are predominantly used for mounting on conductor rails. Through additional potting it is possible to achieve droplet-tightness, as well as greater shock and vibration resistance with mechanical loading (IEC 68). This is the most common and cost-effective form of current transformer. However, the primary conductor must be disconnected during installation. This form of transformer is therefore most commonly used in new system installations.
