Frequently Asked Questions for 3RU2116-1BB00-8K

The SIEMENS 3RU2116-1BB00-8K is a commercial-grade Over Load Relay designed to protect three-phase AC electric motors from continuous overcurrent conditions, thermal degradation, and mechanical stalling. It operates as a Siemens SIRIUS 3RU21 thermal overload relay, optimized for Class 10 protection up to 40A/100A, featuring built-in phase failure protection, ambient temperature compensation, and manual/automatic reset selectors compatible with SIRIUS 3RT contactors. The device is engineered to comply with strict international benchmarks such as IEC/EN 60947-4-1, UL, and CSA standards, making it fully ready for integration into global power grids operating at both 50Hz and 60Hz. Procurement managers can find this authorized switchgear with global shipment support on Electrihub.com.
The SIEMENS 3RU2116-1BB00-8K Over Load Relay continuously monitors phase currents via precisely calibrated internal elements (bimetallic strips or advanced electronic current transformers). In the event of a phase failure or single-phasing condition, the relay triggers an accelerated differential trip response to prevent rapid motor winding insulation breakdown. This action mechanically shifts the auxiliary contact block, opening the contact to break the control circuit coil and closing the contact to signal a system fault, ensuring complete protection across complex global automation networks.
The SIEMENS 3RU2116-1BB00-8K is physically and electrically engineered for direct plug-in mounting to matching SIEMENS power contactor frameworks, optimizing panel space and eliminating unnecessary control wiring. It is certified for both Type 1 and Type 2 coordination schemas under short-circuit conditions when combined with appropriate molded case circuit breakers (MCCBs) or high-capacity fuses. For independent installation profiles, standalone DIN rail or panel baseplates are supported, providing global panel builders on Electrihub with maximum engineering flexibility.
