Siemens 3RB2046-2EW1 S3 Overload Relay 25-100A Class 20

The Siemens 3RB2046-2EW1 is a Size S3 overload relay for motor protection, with a current range of 25 to 100 A and Class 20 tripping characteristics. This unit is designed for stand-alone installation, unlike many other models that mount directly to contactors. It features a straight-through transformer for the main circuit and screw terminals for the auxiliary circuit, supporting both manual and automatic reset. This product is phased out, with the SIRIUS 3RB3 series, specifically the 3RB3046-2XW1, being its successor.

This overload relay is suitable for applications requiring independent mounting and robust motor protection, particularly in environments where direct contactor mounting is not feasible. Its Class 20 rating makes it appropriate for motors with longer acceleration times or higher starting currents. Industries such as mining, heavy manufacturing, and infrastructure projects often utilize such relays for critical machinery like large pumps, crushers, and heavy-duty conveyors.
