Siemens Industrial Controls 3RU2116-1AB0 Relay
The Siemens SIRIUS 3RU2116-1AB0 is a high-precision, thermal-delayed overload relay optimized for current-dependent motor protection. Designed for frame size S00, this Class 10 device provides essential inverse-time delayed protection against excessive temperature rises resulting from overloads or phase failure. With a versatile setting range of 1.1 to 1.6 Amps, it integrates seamlessly with 3RT2015 to 3RT2018 contactors via direct mounting to minimize enclosure footprint and streamline cabinet assembly.
Engineered for industrial reliability, the 3RU2116-1AB0 features bimetal strips that actuate internal auxiliary contacts (1 NO + 1 NC) when current exceeds the set SIRIUS motor protection parameters. This model supports both manual and automatic reset modes, selectable on the front interface, and includes a switch position indicator for clear diagnostic status. The unit is rated for insulation voltages up to 690V and includes an integrated TEST slide to verify the tripping mechanism during maintenance. Its rugged construction ensures stable performance in HVACR motor control environments, providing overcurrent protection across a wide ambient temperature spectrum with effective internal temperature compensation.
Key Benefits:
- Optimized Integration: Specifically designed for direct mounting onto Siemens S00 contactors, reducing wiring time and DIN rail usage.
- Dual Protection Logic: Sophisticated bimetal design provides robust protection against both sustained overloads and damaging phase asymmetry.
- Flexible Reset Options: Toggle between manual reset for locked-out safety protocols or automatic reset for remote, unmanned operation.
- Diagnostic Transparency: Front-facing switch position indicator and TEST function allow technicians to troubleshoot and verify thermal overload status instantly.
- High Environmental Tolerance: Temperature-compensated operation ensures accurate tripping characteristics from -20°C to +60°C.
Common Questions:
Can the 3RU2116-1AB0 be used with single-phase motors?
Yes, while primarily used for three-phase systems, this thermal overload relay can protect single-phase AC or DC loads by wiring the poles in series to ensure all bimetal strips sense the current flow.
How do I set the correct amperage on the dialing knob?
Always match the setting to the Full Load Amps (FLA) listed on the motor nameplate. The 1.1–1.6A range allows for fine-tuning to ensure the motor operates within its thermal limits without nuisance tripping.
What happens during a phase failure?
The integrated differential slider detects the current imbalance. In a phase loss scenario, the relay will trip faster than a standard overload condition to prevent winding damage from increased current in the remaining phases.
