Description

The Siemens 3RU1146-4JB0 overload relay is a robust motor protection device designed for current ratings between 45 to 63 A. As part of the SIRIUS series, it adheres to Class 10 thermal overload standards and is compatible with size S3 installations. Engineered for seamless integration, this relay supports direct mounting onto contactors, featuring both main and auxiliary screw terminals for secure electrical connections.

Equipped with manual and automatic reset functionalities, the unit ensures reliable response in overcurrent scenarios while minimizing downtime. The compact design offers dimensions of 112 x 76 x 131 mm and a net weight of approximately 0.56 kg, ideal for space-constrained industrial environments where efficient assembly is critical.

This product complies with RoHS substance restriction standards post-2006 and meets WEEE take-back obligations under EU directives, affirming its environmental sustainability credentials. While discontinued, this model's preferred successor—SIRIUS type 3RU2136-4JB0—provides equivalent performance enhancements suited for modern applications.

Engineers or distributors reviewing legacy systems may still leverage detailed technical documentation available from Siemens or transition to updated models within the SIRIUS portfolio for long-term operational reliability.
