It operates on 24 V AC/DC supply and provides two CO (changeover) auxiliary contacts for signaling or direct motor starter dropout. The IP20 protected housing uses screw-type terminals for auxiliary and control wiring. This part is a phased-out product. The preferred successor is the 3RN2011-1BA30, which offers a manual/remote reset function and hard gold-plated contacts for improved low-voltage switching reliability. The 3RN2011-1BA30 also operates on 24 V AC/DC and maintains the same 2 CO contact configuration, making it a direct functional replacement for new designs or panel retrofits. The 3RN1011-1GB00 includes a reclosing lockout function, preventing automatic restart after a thermal trip until the motor has cooled and a manual reset is performed. This is critical for applications where unexpected re-energization could cause equipment damage or personnel risk. An integrated LED display provides local status indication of the evaluation unit's operating state, simplifying commissioning and troubleshooting without needing a multimeter.","metaTitle":"Siemens 3RN1011-1GB00 Thermistor Motor Protection, 24 V AC/D","metaDescription":"Siemens 3RN1011-1GB00 thermistor motor protection evaluation unit, 24 V AC/DC, 2 CO contacts, IP20, phased out with successor 3RN2011-1BA30.
