Siemens Industrial Controls 3RV2021-4BA10 Breaker
The Siemens 3RV2021-4BA10 is a specialized SIRIUS motor starter protector designed for the heavy-duty demands of industrial motor control. Built on the S0 frame size, this 3-pole circuit breaker provides comprehensive Type E motor protection, serving as a self-protected combination motor controller. It features an adjustable thermal overload release with a range of 13 to 20 Amps, allowing for precise calibration to match specific motor full-load currents. The integrated magnetic short-circuit trip is fixed at 260A to handle high inrush currents without nuisance tripping during startup.
This unit is engineered for standard switching capacity and is optimized for IE3/IE4 motors, ensuring performance in high-efficiency electrical systems. The screw terminal design provides a secure, vibration-resistant connection for 14-8 AWG power wiring. With a Class 10 trip characteristic, it ensures a reliable shutdown within 10 seconds under overload conditions. The manual rotary handle offers clear status indication and a lockable off-position for safe maintenance protocols. For contractors, the compact 45mm width allows for seamless integration with 3RT2 contactors using 3RA29 link modules to create space-saving load feeders on standard 35mm DIN rail.
Key Benefits- Dual-Function Protection: Combines adjustable thermal overload and magnetic short-circuit protection in a single compact motor circuit breaker.
- Space Optimization: The SIRIUS 3RV2 series compact design minimizes control cabinet footprint while replacing separate overload relays and breakers.
- Versatile Compatibility: Designed for use in load feeders, group installations per NEC 430-53(C), and as a standalone manual motor controller.
- Low Energy Consumption: Advanced bi-metal technology reduces power loss by 5-10% compared to previous generations, decreasing heat buildup in the panel.
Is this unit phase-loss sensitive?
Yes, the 3RV2021-4BA10 is phase-loss sensitive and will trip to protect the motor in the event of a single-phasing condition.
Can I add auxiliary switches to this breaker?
Absolutely. You can field-install lateral or transverse auxiliary contacts to provide remote signaling or secondary control logic state feedback.
What is the maximum voltage rating?
This manual motor starter is rated for operational voltages up to 690V AC, making it suitable for standard global power distributions.
