Product Overview

The Siemens 3RN2011-1BA30 is a SIRIUS 3RN2 thermistor motor protection relay designed to monitor motor temperature through PTC thermistor sensors. The standard evaluation unit uses a 24V AC/DC control supply and features two changeover relay contacts for integration into industrial motor control circuits. Its 22.5mm housing and screw terminal connections support compact control cabinet installations. The relay provides manual and remote reset, READY and TRIPPED LED indication, a TEST/RESET button, and integrated thermistor circuit monitoring for wire-break and short-circuit conditions. The manufacturer specifies ATEX approval for the applicable motor protection arrangement. For this 3RN2011 version, remote reset is performed by interrupting and restoring the control supply. Actual product and packaging photographs show the matching catalog number 3RN2011-1BA30. Confirm sensor compatibility, contact ratings and the required protection arrangement before installation.
