Tests and measurements of separate circuits within electrical switchgear and electrical installations are subject to normative requirements DIN or also DIN VDE. Test disconnect terminal blocks and neutral disconnect terminal blocks (N-disconnect terminals) are used to safely disconnect a circuit on a terminal without disconnecting the connected conductor for this purpose.
Various designs and versions (color, type of connection, cross-section) of the terminals enable the circuit to be separated or contacted to the 10x3 electrical busbar or N busbar, for example, for an insulation resistance measurement, which is required by VDE in public facilities. The opening and closing of the disconnect lever, slider or N-slider can be realized easily and safely with a screwdriver.
On the website Engineering Data you will find an extensive selection of downloads related to CAT data. For the quick integration of our products into your design, a wide range of digital product data is available for engineering systems such as EPLAN (EPLAN Electric P8 and EPLAN Pro Panel), Zuken E3.series, WSCAD and many others. These data allow a precise representation of disconnect terminal blocks, test disconnect terminal blocks or also N-wire disconnect terminal blocks (blue) in 3D and show all relevant electrotechnical and business characteristics.
