The Siemens 3RN1010-1GB00 is a thermistor motor protection evaluation unit from the SIRIUS 3RN1 series. The unit is housed in a 22.5 mm wide enclosure rated IP20, with screw-type terminals and an LED display for status indication.
This part is marked as a phased-out product. The preferred successor is the 3RN2010-1BA30, a thermistor motor protection standard evaluation unit with auto-reset, 2 W, hard gold-plated contacts, and 24 V AC/DC supply. For existing BOM lines or installed panels, the 3RN1010-1GB00 can be sourced to order through independent channels; an RFQ is required to confirm availability and lead time.
Key Ratings & Fit
The ambient operating range spans -25 to +60 °C, suitable for most industrial cabinet environments. The 22.5 mm width fits standard DIN-rail spacing, and the unit can be screw-mounted or snap-mounted onto the rail. Two CO contacts give flexibility for both normally-open and normally-closed signaling without additional auxiliary contact blocks.
