SIEMENS 3UX1425

<h2>Siemens 3UX1425 Terminal Support for 3UA55 Overload Relays</h2> <h3>Description</h3> <p>The Siemens 3UX1425 is a terminal support designed for the separate mounting of 3UA55 thermal overload relays. This adapter provides the flexibility to install the overload relay on a standard DIN rail or screw-mount it directly onto a control panel, independent of a contactor. It is a vital component for maintaining legacy systems that utilize the robust but obsolete 3UA55 series, ensuring proper and secure electrical connections in various industrial applications.</p> <h3>Specifications</h3> <ul> <li>Manufacturer: Siemens</li> <li>Type Number: 3UX1425</li> <li>Product Type: Terminal Support for Separate Mounting</li> <li>Compatibility: Specifically for Siemens 3UA55 series overload relays</li> <li>Mounting Style: DIN Rail or Screw Mount</li> </ul> <h3>Label Info</h3> <ul> <li>Instr.Ord.No.: 3ZX1012-0UX14-1AA1</li> <li>EAN: 4011209066441</li> </ul> <h3>Application</h3> <p>This terminal support is used in industrial control panels for motor control applications where a 3UA55 overload relay needs to be mounted separately from its associated contactor. This is common in custom panel designs, retrofit projects, or for maintenance and repair of existing machinery.</p> <h3>Country of Origin</h3> <p>Made in Germany.</p> <h3>CO2 Impact</h3> <p>Reusing this component saves approximately 4.0 kg of CO2, contributing to a more sustainable industrial environment by extending the life of existing equipment and reducing manufacturing demand.</p> <h3>Availability</h3> <p>This is an obsolete item, available as New Old Stock (NOS).

This is useful for custom panel layouts or when the relay needs to be physically distant from the contactor.</p> <strong>Is this terminal support compatible with the modern SIRIUS overload relays like the 3RU2 series?</strong><br><p>No, the 3UX1425 is specifically designed for the obsolete 3UA55 series. Modern SIRIUS relays like the 3RU2 or 3RB3 series require their own specific terminal supports, such as the 3RU29 models.</p> <strong>What are the mounting options for a 3UA55 relay using this support?</strong><br><p>This support provides two mounting options: it can be snapped onto a standard 35mm DIN rail or it can be screw-mounted directly onto a panel using the provided mounting holes.</p> </p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
