Siemens Industrial Controls 3RU2136-4GB0 Relay
The Siemens 3RU2136-4GB0 is a high-performance thermal overload relay engineered for heavy-duty motor protection within HVACR and industrial control systems. Designed specifically for SIRIUS size S2 applications, this unit provides precise monitoring for motors with a current rating between 36 and 45 Amps. The Class 10 tripping characteristic ensures reliable downtime prevention by responding to overcurrent and phase failure conditions before insulation damage occurs on the windings.
Built for efficiency, the 3RU2136-4GB0 features screw-clamp terminals for both the main and auxiliary circuits (1 NO + 1 NC), ensuring vibration-proof connections in high-use environments. The integrated phase loss protection and manual/automatic reset options allow contractors to tailor protection to specific field requirements. This relay is optimized for direct mounting onto SIRIUS 3RT203 contactors, streamlining assembly in control panels while maintaining a compact footprint.
- Optimized Motor Safety: Features Class 10 trip curves and adjustable current settings (36-45A) for precise thermal protection.
- Versatile Reset Modes: Switchable between manual, automatic, and remote reset to decrease system downtime.
- Full Phase Protection: Built-in phase failure sensitivity protects against asymmetrical current and single-phase operation.
- Secure Interfacing: Screw terminals provide high clamping force for heavy-gauge wiring in demanding HVACR installations.
- SIRIUS System Compatibility: Seamlessly mounts to 3RT2035, 3RT2036, 3RT2037, and 3RT2038 contactors.
Common Questions
Is the 3RU2136-4GB0 compatible with older Siemens contactors?
This relay is specifically designed for the SIRIUS 3RT203 (Size S2) family. For older 3RT10 series or stand-alone mounting, a separate terminal support block is required.
How do I configure the reset function?
The blue reset button on the front can be set to "M" for manual reset or "A" for automatic reset by rotating the selector. Manual mode is recommended for troubleshooting to ensure the fault is cleared before restarting.
Does this unit protect against phase imbalance?
Yes, it includes phase failure protection as standard, which significantly increases the sensitivity of the internal bi-metals during an imbalance or loss of phase.
