Siemens Industrial Controls 3RV2021-4CA10 Motor Starter
The Siemens 3RV2021-4CA10 is a heavy-duty SIRIUS 3RV2 motor starter protector engineered for precise motor protection and switching in industrial load feeders. This size S0 manual motor starter features a wide thermal adjustment range of 17-22A, allowing for exact calibration to the motor's Full Load Amps (FLA) via the integrated rotary handle. Designed for three-phase motors up to 11kW at 400V, it provides reliable Class 10 overload trip characteristics, ensuring circuit interruption in under 10 seconds during overcurrent events. As a UL-approved Type E self-protected combination motor controller, the 3RV2021-4CA10 consolidates disconnect, short-circuit, and overload protection into a single compact device. Built with robust screw terminals and designed for standard 35mm DIN rail mounting, this unit is climate-resistant and optimized for close-coupled mounting with 3RT2 contactors. It features a fixed magnetic short-circuit release 13 times the maximum current setting and is sensitive to phase loss to prevent winding damage in unbalanced current conditions.
Key Benefits- Multifunctional Performance: Certification as a Type E self-protected combination motor controller means this single unit handles disconnect, short-circuit, and overload protection.
- Precise Current Monitoring: Adjustable thermal overload release between 17A and 22A facilitates accurate field settings for various motor sizes.
- Industrial Durability: Offers a high short-circuit breaking capacity of 65kA at 480V, ensuring safety in demanding HVACR and industrial environments.
- Compact Integration: Part of the SIRIUS innovation system, allowing for screw-terminal mounting and seamless physical integration with 3RT2 series contactors.
- Can this be used for single-phase motor protection? While primarily designed for three-phase motors, it can be used for single-phase loads if all three poles are wired in series to satisfy the phase-loss sensitive detection logic.
- Is an additional terminal block required for Type E applications? Yes, for UL 508 Type E compliance, an additional large infeed terminal (like the 3RV2928-1H) is typically required to maintain essential clearances.
- What mounting orientation is supported? This motor starter is designed for vertical or horizontal mounting on 35mm DIN rail, though vertical mounting is standard for optimal thermal dissipation.
