It monitors motor winding temperature via PTC thermistors and trips the contactor on over-temperature, providing a reclosing lockout function so the motor cannot restart until the fault is manually reset. The 110 V AC supply voltage is the operating coil voltage — confirm your control circuit matches. The unit accepts 50 Hz or 60 Hz without adjustment. The 22.5 mm width matches standard DIN-rail component spacing, so it occupies one modular slot in a panel. The unit provides two changeover (CO) auxiliary contacts for status feedback. No normally-open or normally-closed dedicated contacts are present — the two CO contacts handle both signalling and lockout indication. The 3RN1011-2BG00 is a phased-out product. The manufacturer's preferred successor is the 3RN2011-2BW30, a thermistor motor protection standard evaluation unit with manual/remote reset and 2 W consumption at 110 V AC. For new designs or BOM lines that cannot accept the successor, the 3RN1011-2BG00 is sourced through our surplus and last-time-buy channels. The 91 mm depth fits standard 100 mm deep enclosures. Spring-loaded terminals accept solid or ferruled conductors; strip length 8 mm. No auxiliary power supply needed — the unit is self-powered from the 110 V AC control circuit.","metaTitle":"Siemens 3RN1011-2BG00 Thermistor Motor Protection, 110 V AC","metaDescription":"Siemens 3RN1011-2BG00 thermistor motor protection evaluation unit. 110 V AC, 50/60 Hz, IP20, spring terminals.
