Distribution connector WINSTA ® MIDI B coding
Use effective pluggable connections instead of laborious screw connections: With the WINSTA ® MIDI distribution connector 4-pole. Whether on PCBs, in control cabinets or for connecting lights – pluggable installation connectors from WAGO allow you to make connections according to an enormous variety of requirements in next to no time. For greater protection in electrical installations, the pluggable installation connector is equipped with mechanical 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 elements. Solutions like the WINSTA ® MIDI pluggable installation connectors with B coding are suitable for process control, for example, for lighting or in data networks. This pluggable installation connector is designed for a voltage load of up to 25 A. As a result, it can also be used for high power loads. WINSTA ® MIDI with Push-in CAGE CLAMP® spring pressure connection technology is used in a broad range of individual products you can use for quick, easy and maximally flexible installation.
Lower costs through fast commissioning and elimination of service expenses – solutions from WINSTA ® MIDI
The WINSTA® Pluggable Connection System is ideally tailored to the very strict requirements of building installation. It makes electrical installation pluggable, and consequently more efficient, even more reliable, and error-free. Using this pre-assembled system decreases assembly times and installation errors at the construction site. Choose quality and durability – with marking from WAGO makes the electrical installation of electrical components noticeably easier.
