<h2>Female connector/socket <i>WINSTA</i>® MIDI rated current 25 A</h2><br/><br/>Use effective pluggable connections instead of laborious screw connections: With the <i>WINSTA</i>® MIDI female connector/socket 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 many different requirements in seconds. The coding options reduce installation errors, allowing fast, secure wiring of all components. The pluggable installation connector is protected in accordance with protection type IP20 (When mated and secured with a strain relief housing: 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 energised contact elements. The <i>WINSTA</i>® MIDI pluggable installation connector with A coding in white or black is usually used for general mains applications in power distribution. This pluggable installation connector can be employed for a voltage load of up to 25 A. Therefore, 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. Due to the built-in test slot, connections can be checked even when they are plugged in. This saves time, labor, and money.<br/><br/><h3><i>WINSTA</i>® MIDI solutions for your electrical installation – protected against mismating and maintenance-free</h3><br/><br/>WINSTA® is the pluggable connection system that is perfectly tailored to the strict requirements of electrical installation. It allows error-free installation of cables and components, quickly and reliably. Now you can also cut installation costs without compromising safety and quality: with protection type IP20 eliminates the need for servicing and prevents unnecessary downtime. <br/><br/><ul><br/><li>effective protection against mismating</li><li>simple circuits</li><li>for any mains application</li><li>custom-engineered solutions</li><li>convenient installation and commissioning</li></ul>
