Siemens Industrial Controls 3RV2021-1FA10 Protector
The Siemens 3RV2021-1FA10 is a heavy-duty SIRIUS 3RV2 Motor Starter Protector specifically engineered for modern industrial motor control and load feeder applications. As a Size S0 manual motor starter, it provides integrated short-circuit and thermal overload protection within a single, compact frame. This unit features an adjustable thermal-magnetic trip range between 3.5 and 5A, making it ideal for precision motor balancing and Type E self-protected combination motor controller configurations. Designed with Class 10 tripping characteristics, it ensures high-efficiency motors remain protected under rigorous startup conditions.
Built for the professional contractor, the Siemens 3RV2021-1FA10 utilizes robust screw connection terminals to maintain a steady, vibration-proof link in high-stress environments. With a 100kA short-circuit breaking capacity at 400V and an instantaneous magnetic release set at 65A, this 3-pole motor circuit breaker offers superior reliability. It is fully compatible with the broader SIRIUS modular system, allowing for the direct integration of auxiliary switches, signaling contacts, and 3RT2 contactors for a complete automation solution.
Key Benefits
- Optimized Motor Protection: Fully adjustable setting scale (3.5A to 5A) allows for precise matching to motor Full Load Amperage (FLA).
- High Breaking Capacity: Rated for up to 100kA at 400V, ensuring safety during extreme fault conditions.
- Industrial Durability: Ambient temperature compensation up to 140°F (60°C) allows for consistent operation in dense control panels.
- Phase Failure Sensitivity: Includes built-in protection against single-phasing to prevent motor winding burnout.
- Versatile Mounting: Standard 35mm DIN rail mounting for rapid field installation and replacement.
Common Questions
Can I use this for IE3/IE4 high-efficiency motors?
Yes, the 3RV2 series is specifically designed and certified for the higher inrush currents associated with IEC-60034-30 class motors.
Is an external overload relay required with the 3RV2021-1FA10?
No, this device functions as a manual motor protector with built-in thermal and magnetic trip elements, eliminating the need for a separate overload relay in many branch circuit designs.
What is required for a UL Type E installation?
To meet Type E self-protected combination controller requirements in the US, a terminal adapter (such as the 3RV2928-1H) is typically required to increase clearances at the line side.
