<h2>Distribution connector <i>WINSTA</i>® MIDI rated current 25 A</h2><br/><br/>The <i>WINSTA</i>® MIDI distribution connector 3-pole supports fast, reliable installation. WAGO pluggable installation connectors are useful when criteria repeat or are distributed on a specific pattern, for example for installing grid lighting or flush-mount lighting. For greater security in electrical installations, the pluggable installation connector is provided with mechanical protection against mismating. The pluggable installation connector offers touch-proof protection with live components in accordance with protection type IP20 (When mated: IP2xC (These compact connectors are not designed for use in open, easily accessible areas!)). The <i>WINSTA</i>® MIDI pluggable installation connector with A coding in white or black is normally used for general mains applications in power distribution. This pluggable installation connector is designed for a voltage load of up to 25 A. Thus, it can also be used for high power loads. The <i>WINSTA</i>® MIDI Pluggable Connection System with Push-in CAGE CLAMP® spring pressure connection technology facilitates exemplary electrification. Thanks to the built-in test slot, connections can be checked even when they are plugged in. That saves time and reduces installation labor and costs.<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 allows pluggable electrical installation. This saves time, lowers costs, and reduces the need for servicing. Choose durability and quality – with protection against mismating from WAGO makes the electrical installation of electrical components noticeably easier. <br/><br/><ul><br/><li>effective protection against mismating</li><li>for automation controllers</li><li>with A coding for a great number of applications</li><li>ready for immediate use</li><li>quick replacement of defective units during ongoing operation</li></ul>
