The Siemens 3UA5900-1A is a thermal time-delayed overload relay designed for reliable motor protection in industrial control applications. This unit is intended for installation as a single, standalone device and is well suited for integration into motor starter and control panel assemblies.


With an adjustable current setting range from 1 to 1.6 A, the relay provides accurate protection against overload conditions by responding to excessive current over time. The thermal tripping mechanism ensures dependable operation in demanding environments, helping to prevent motor damage and unplanned downtime.


The device is equipped with one normally open (1NO) and one normally closed (1NC) auxiliary contact, allowing flexible signaling and control circuit integration. Manufactured by Siemens in Germany, this overload relay reflects proven engineering quality and compliance with industrial standards.


Please note that this product is marked as obsolete. It may still be suitable for maintenance, replacement, or retrofit purposes within existing installations where compatibility is required.
