Weidmuller disconnect terminals
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.
Weidmuller 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.

SFS and SDT functional terminal blocks with SNAP IN connection technology
Sensors and actuators can be wired safely and quickly with a simple "CLICK". The compact Klippon® Connect fuse and disconnect terminal blocks are now also available with the innovative SNAP IN connection system. A special feature of the terminal blocks is the wide range of cross-connection options, which are located in front of and behind the separate or security area. These offer maximum flexibility to easily and reliably multiply potentials or signals - perfectly matched to the growing requirements and variety of signals in modern panel building.

PUSH IN - disconnect terminal blocks with 3.5 mm width
Our ADT 1.5 disconnect terminal blocks offer the option of disconnecting signals up to 10 A with a minimum width of just 3.5 mm. Integrated and standardized testing points in front of and behind the disconnection area enable simple and safe testing and inspection in the field, even when wired.

Test disconnect and fuse terminal blocks A2T 4 FS and A2T 4 DT
The number of sensors and actuators in the field is growing. More and more potentials have to be wired, fused, or even separated in the control cabinet. One example is servomotors with the potentials plus, minus, or PE. They require clear wiring, including fused potential.
The new two-tier terminals of the A2T 4 FS and A2T 4 DT series combine up to three functions per terminal. For example, you can choose between "Disconnect, feed through, PE" or "Fuse, feed through, PE" Sensors and actuators can be wired conveniently and clearly on just one terminal block. The potentials can be fused or also disconnected. Cross-connection channels on each level ensure safe potential distribution on the terminal strip.

Separate potentials simply and safely in confined spaces
In marshalling cabinets of industrial control systems, signal lines from the field are often connected with terminal blocks. These are known as a robust, simple, and tidy connection option. However, their use requires sufficient current protection and a reliable disconnection circuit.
Our A2T 2.5 DT/DT test-disconnect terminal blocks enable safe and simple electrical isolation in confined spaces. Two potentials can be operated with only one terminal block, resulting in space savings of 50%. The multifunctional disconnect section can be converted into a fuse terminal or equipped with a component plug to enable the integration of electronic components.
