Siemens Industrial Controls 3RV2021-4AA10 Protector
The Siemens 3RV2021-4AA10 is a heavy-duty SIRIUS 3RV2 motor starter protector designed for precise motor protection in demanding industrial and HVACR environments. This size S0 manual starter is engineered with a thermal-magnetic trip unit, providing an adjustable 11-16A FLA (Full Load Amps) range to match specific motor requirements. It serves as a comprehensive branch circuit solution, integrating short circuit protection, disconnect functions, and overload protection into a single UL-listed Type E self-protected combination motor controller. With a Class 10 trip characteristic and phase loss sensitivity, this device ensures rapid response to electrical faults, safeguarding your equipment from costly downtime.
Built for the technician’s workflow, the 3RV2021-4AA10 features screw terminals for secure wiring and a standardized 35mm DIN rail mounting footprint for easy integration into existing control panels. The unit includes a rotary handle with a clear ON/OFF/TRIPPED status indicator and a built-in lockout mechanism for safe maintenance. Capable of handling a short-circuit breaking capacity of up to 65kA at 480Y/277V, it is the professional choice for protecting 3-phase motors up to 7.5kW at 400V. For expanded functionality, it is fully compatible with lateral auxiliary switches and 3RT2 series contactors.
Key Benefits- Enhanced Equipment Safety: Features phase loss protection and ambient temperature compensation up to 140°F to maintain reliability in hot mechanical rooms.
- Space-Saving Design: The compact S0 frame size replaces multiple components by acting as a manual motor starter and branch circuit protector.
- Reliable Trip Logic: Class 10 overload trip ensures your motor is disconnected in under 10 seconds during an overcurrent event.
- Industry Compliance: Meets UL 60947-4-1 standards as a Type E combination motor controller when used with appropriate terminal adapters.
What is the maximum voltage rating for this protector?
The 3RV2021-4AA10 is rated for a maximum operating voltage of 690V AC, making it suitable for both standard and high-voltage industrial applications.
Can I add auxiliary contacts to this unit?
Yes, this Siemens Motor Starter Protector supports various SIRIUS 3RV29 accessories, including front-mounted or lateral auxiliary switches for remote signaling and status monitoring.
What is the difference between this and the older 3RV1 series?
This 3RV2 series unit provides improved energy efficiency and is a direct, higher-performance replacement for the obsolete 3RV1021-4AA10 model.
