An earth terminal block is a protective feed-through terminal with PE function (ground), i.e. an electrically conductive connection to the DIN rail / DIN mounting rails. The protective earth terminal blocks have one or more connection points and are available as single-level PE terminal blocks, multi-level ground terminal block (double-level terminal blocks and three-level terminal blocks). Some of our terminals in combination with our DIN rails / top-hat rails offer the possibility of separating the PEN conductor, i.e. the PEN function within the switchgear.
DIN rails and C profiles can also be used as protective earth busbars (PE conductors) or PEN conductors under certain conditions. Weidmüller's PE ground terminal with spring and screw connections meet the requirements for PE wires specified in IEC 60947-7-2. According to VDE 0100 Part 540, protective earth conductors and neutral conductors with wire cross-sections above 10 mm2 may be combined to form a conductor abbreviated as PEN.
Modular earth conductor terminal blocks provide the electrical and mechanical connection between copper conductors and the mounting support. They have one or more clamping points for connection to and/or branching of predective conductors. The power terminals with predective conductor functions comply with the IEC 60947-7-2 standard.
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. This data enables a precise representation of the earth terminal block and earth disconnect terminal blocks in 3D and shows all relevant electrotechnical and operational characteristics.
