Stopfen (electrical plug) with brass contact and screw connection Key benefits Reliable electrical contact: solid brass contact material provides consistent conductivity and good corrosion resistance for long-term performance. Secure mechanical connection: screw-type connection locks the conductor in place to reduce loosening from vibration or handling. Easy to install and service: straightforward screw terminal makes wiring, replacement, and maintenance quick with common tools. Versatile use: compact design suits a range of screw-terminal applications where a reliable plug/stopfen is required. What it is and how it works Function: a stopfen (plug) designed to make or close an electrical connection through a screw terminal. The brass contact is the conductive element; the screw connection clamps the wire or mating part. Material: contact material is brass (Messing) for stable electrical contact and wear resistance. Connection type: screw (Schraube) for secure, adjustable clamping of conductors. Compatibility and performance notes Fits systems and assemblies that accept screw-type plug/stopfen components. Check that terminal geometry and conductor size match your application before installation. Brass contact minimizes contact resistance and helps maintain reliable conductivity under typical operating conditions. Suitable for repeated installation/removal where a durable electrical contact is needed. Typical applications Control panels and distribution boxes: use as a replacement plug or to terminate a screw-terminal position during assembly or service. Machine and equipment wiring: secure a conductor in equipment harnesses where a screw-type plug provides the needed connection and mechanical stability. Maintenance and repair: restore a damaged or missing plug on terminal strips, enclosures, or modular connectors that use screw-clamped contacts. Installation tips Ensure the terminal and conductor sizes are compatible before tightening. Tighten the screw firmly to secure the conductor, but avoid over-torquing to prevent damage to the contact or terminal. Inspect the brass contact for cleanliness and proper seating to ensure low contact resistance.
