Weidmueller VRSTI/1,5-2,5

The Weidmüller VRSTI/1,5-2,5 is likely a crimp-style cable lug or connector designed for cables with a cross-sectional area between 1.5 and 2.5 mm².  The "VRSTI" prefix probably denotes a specific product series within Weidmüller's catalog. These connectors are used for creating secure and reliable electrical connections, often in industrial settings.  Because they are crimp-style, they require a specialized crimping tool for proper installation.  For detailed specifications, materials, and appropriate applications, it's best to consult the official Weidmüller documentation or contact their customer support.
