Siemens 3RB2046-2EB0 S3 Overload Relay 25-100A Class 20

The Siemens 3RB2046-2EB0 is a Size S3 overload relay engineered for motor protection, covering a current range of 25 to 100 A with Class 20 tripping characteristics. It supports both manual and automatic reset functionalities and is designed for direct mounting on contactors. The main circuit utilizes screw terminals, while the auxiliary circuit is also equipped with screw terminals for easy and secure connections. This model is a phased-out product, with the SIRIUS 3RB3 series, specifically the 3RB3046-2XB0, serving as its successor.

This overload relay is essential for protecting motors in applications where slightly longer start-up times or higher inrush currents are expected, due to its Class 20 rating. It is commonly employed in industries such as manufacturing, material handling, and water treatment, safeguarding equipment like pumps, fans, and conveyors from thermal damage and overloads. Its reliability ensures consistent operation and minimizes the risk of costly motor failures.
