Description
The Siemens 3RU2116-1AB0 is a thermal overload relay designed to provide reliable motor protection against sustained overload conditions, phase failure, and phase imbalance. Part of the Siemens 3RU2 series, this relay is engineered for direct mounting onto Siemens 3RT2 contactors, making it an ideal solution for compact motor starter assemblies in commercial and industrial HVAC applications.
Key Features
- Current setting range: 1.1–1.6A for precise motor protection
- Thermal overload protection guards against motor burnout from sustained overcurrents
- Phase failure and phase imbalance sensitivity for three-phase motor protection
- Direct mounting onto Siemens 3RT2 contactors for space-saving installation
- Manual and automatic reset modes for flexible operation
- Integrated test and reset button for easy commissioning and maintenance
- Auxiliary contacts included for control circuit integration (1 NO + 1 NC)
- Trip class Class 10A for standard motor applications
Application
The 3RU2116-1AB0 is well-suited for protecting small single-phase and three-phase motors in HVAC equipment including fans, pumps, compressors, and air handling units. Its compact design and direct contactor mounting simplify panel layout and reduce wiring complexity in motor control centers and starter panels.
