<h2>Distribution connector <i>WINSTA</i>® MIDI 5-pole</h2><br/><br/>For power and signal transmission: The <i>WINSTA</i>® MIDI distribution connector with protection type IP20. Whether on PCBs, in control cabinets or for connecting lights – pluggable installation connectors from WAGO allow you to establish connections according to a huge variety of requirements in no time flat. For greater security in electrical installations, the pluggable installation connector is provided with mechanical protection against mismating. The pluggable installation connector is protected in accordance with protection type IP20 (When mated: IP2xC (These compact connectors are not designed for use in open, easily accessible areas!)). This means that users' fingers will never come into contact with live elements. Thanks to the color coding and mechanical A coding of <i>WINSTA</i>® MIDI pluggable installation connectors, you can clearly distinguish different circuits. This pluggable installation connector can be used for electrical currents up to 25 A. Thus the product is also suitable for high power loads. The <i>WINSTA</i>® MIDI product line guarantees flexibility for the electrical installation. Through its Push-in CAGE CLAMP® spring pressure connection technology, it guarantees error-free, time-saving installation and offers customization and flexibility for meeting various installation requirements.<br/><br/><h3>Lower costs through fast commissioning and elimination of service expenses – solutions from <i>WINSTA</i>® MIDI</h3><br/><br/>The WINSTA® Pluggable Connection System is ideally tailored to the very strict requirements of building installation. It makes electrical installation pluggable, and therefore faster, even more reliable, and error-free. Use of this pre-assembled system decreases time spent on assembly and installation errors at the construction site. Now you can also lower installation costs without compromising safety and quality: with protection against mismating reduces the need for servicing and prevents unnecessary downtime. <br/><br/><ul><br/><li>pluggable installation connectors with protection against mismating</li><li>pre-assembled versions</li><li>with A coding for use in a large number of general mains applications</li><li>exact dimensions</li><li>quick replacement of defective units during ongoing operation</li></ul>
