<h2>Distribution connector <i>WINSTA</i>® MIDI rated current 25 A</h2><br/><br/>The <i>WINSTA</i>® MIDI distribution connector with protection against mismating is the pluggable solution for your application in control cabinets, for lighting connections or on PCBs. On PCBs, in control cabinets or for connecting lights – pluggable installation connectors from WAGO allow you to make connections according to many different requirements in next to no time. The coding options reduce installation errors, allowing fast, maintenance-free wiring of all components. 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 suitable for process control, for example, for lighting or within data networks. This pluggable installation connector can be used for electrical currents up to 25 A. Thus the product is especially suitable for high power loads. The <i>WINSTA</i>® MIDI Pluggable Connection System with Push-in CAGE CLAMP® spring pressure connection technology facilitates precise electrification. Due to the integrated test slot, connections can be checked even when they are plugged in. That saves time and reduces installation labor and expense.<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 strict requirements of building installation. It makes electrical installation pluggable, and consequently more efficient, 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 reduce installation costs without compromising quality and safety: with locking lever 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 B coding for controllers, for example sun blinds and lighting fixtures</li><li>custom-engineered solutions</li><li>quick replacement of defective units during ongoing operation</li></ul>
