<h2>Distribution connector <i>WINSTA</i>® MIDI A coding</h2><br/><br/>The <i>WINSTA</i>® MIDI distribution connector A coding is the pluggable solution for your use in control cabinets, for lighting connections or on PCBs. Our pluggable installation connectors with spring pressure connection technology function without screw connections. They allow flexible, error-free installation in a large number of applications. The mechanical coding and color coding of the pluggable installation connector ensure error-free installation of the individual components – including 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!)). That results in the fact that users' fingers will never come into contact with live contact elements. Standard mains applications for almost any domain of use can be implemented with <i>WINSTA</i>® MIDI pluggable installation connectors with A coding. The rated current and voltage are important criteria for selecting a pluggable installation connector: They provide information about possible domains of use and applications. This product has a current rating of 25 A – as a result it is also suitable for powerful loads. The <i>WINSTA</i>® MIDI Pluggable Connection System with Push-in CAGE CLAMP® spring pressure connection technology facilitates safe electrification. Due to the integrated test slot, connections can be checked even when they are plugged in. This saves time, labor, and money.<br/><br/><h3>Push-in CAGE CLAMP® spring pressure connection technology – pluggable installation instead of laborious screw connections!</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 faster, even more reliable, and error-free. Use of this pre-assembled system decreases assembly times and installation errors at the construction site. Now you can also reduce installation costs without compromising quality and safety: with protection against mismating reduces the need for servicing and prevents unnecessary downtime. <br/><br/><ul><br/><li>effective protection against mismating</li><li>pre-assembled versions</li><li>with A coding for a great number of uses</li><li>flexible installation to save space</li><li>quick replacement of defective units during ongoing operation</li></ul>
