<h2>Distribution connector <i>WINSTA</i>® MIDI 4-pole</h2><br/><br/>The <i>WINSTA</i>® MIDI distribution connector with locking latch provides the foundation for installation of fine-stranded and solid conductors. The pluggable installation connectors with spring pressure connection technology work completely without screw connections. They allow flexible, error-free installation in numerous applications. For greater protection in electrical installations, the pluggable installation connector is equipped with mechanical protection against mismating. The pluggable installation connector is protected against ingress by solid objects in accordance with protection type IP20 (When mated: IP2xC (These compact connectors are not designed for use in open, easily accessible areas!)). Solutions like the <i>WINSTA</i>® MIDI pluggable installation connectors with B coding are appropriate for applications involving process control, for example, for lighting or in data networks. This pluggable installation connector can be used for electrical currents up to 25 A. Thus the product is also suitable for high power loads. <i>WINSTA</i>® MIDI with Push-in CAGE CLAMP® spring pressure connection technology is found in a broad range of individual products you can use for quick, easy, secure, tailored electrical installation.<br/><br/><h3><i>WINSTA</i>® MIDI solutions for your electrical installation – protected against mismating and maintenance-free</h3><br/><br/>The WINSTA® Pluggable Connection System is perfectly tailored to the very strict requirements of building installation. It makes electrical installation pluggable, and thus faster, more reliable, and error-free. Using this pre-assembled system reduces assembly times and errors during installation at the construction site. Now you can also cut installation expenses without compromising safety and quality: with locking lever reduces the need for servicing and prevents unnecessary downtime. <br/><br/><ul><br/><li>protection against mismating eliminates errors</li><li>simple circuits</li><li>with B coding for use in process automation, such as lighting technology, for instance</li><li>exact dimensions</li><li>convenient installation and commissioning</li></ul>
