Siemens Industrial Controls 3RV2011-4AA10 Breaker

The Siemens 3RV2011-4AA10 is a heavy-duty SIRIUS 3RV2 motor starter protector designed for professional-grade motor protection in industrial HVACR and control environments. This circuit breaker size S00 unit features a precision adjustment range of 11 to 16 Amps FLA, making it ideal for managing inductive loads and induction motors up to 7.5 kW at 400V. Built with screw terminals for secure, high-vibration connectivity, this device integrates essential branch circuit functions—including disconnect, short-circuit protection, and Class 10 thermal overload protection—into a single compact 45mm housing. With a type E self-protected combination motor controller UL rating, it simplifies panel design by reducing the need for additional upstream protection components.

Key Benefits

• Integrated Functionality: Combines manual motor starting, overload protection, and short-circuit interruption (208 A trip) in one DIN-rail mounted device.
• Phase Loss Sensitivity: Built-in protection against single-phase conditions to prevent motor burnout and downtime.
• High Durability: Rated for a mechanical and electrical service life of 100,000 operating cycles under standard load conditions.
• Flexible Mounting: Standard 35mm DIN rail snap-on mounting allows for rapid installation and modular expansion with SIRIUS 3RT2 contactors.
• Clear Diagnostics: Features a rotary handle with lockout capability and visible trip indication for fast troubleshooting on the shop floor.

Common Questions

Is the 3RV2011-4AA10 compatible with 3RT2 contactors?
Yes, this S00 frame size MSP is designed to link directly with Siemens 3RT201 contactors using standard link modules for a seamless, fuseless load feeder assembly.

Can this breaker be used for single-phase motor protection?
While designed for three-phase systems, it can protect single-phase motors if the three poles are wired in series to ensure the phase-loss sensitive mechanism functions correctly.

What is the maximum voltage rating for this motor starter protector?
The unit is rated for an operational voltage of up to 690 V AC, covering standard 230V, 460V, and 575V industrial applications.
