Siemens Industrial Controls 3RV2021-1CA10 Breaker
The Siemens 3RV2021-1CA10 is a specialized SIRIUS motor starter protector designed for professional-grade HVACR and industrial motor control. Built for size S0 systems, this 3-pole circuit breaker provides precision motor protection with an adjustable thermal-magnetic trip range of 1.8 to 2.5 Amps. Engineered to handle high-efficiency IE3/IE4 motors, it features Class 10 tripping characteristics to ensure reliable shutdown within 10 seconds during an overcurrent event. The 3RV2021-1CA10 is UL approved as a Type E self-protected combination motor controller, integrating disconnection, short-circuit protection, and motor control into one compact 45mm width device. With a short-circuit breaking capacity of up to 100 kA at 400V and secure screw terminals, this unit is built for rugged environments requiring high vibration resistance and maintenance-free operation.
Key Benefits- Enhanced HVACR Reliability: Optimized for modern IE3/IE4 motors with low heat loss, maintaining efficiency in densely packed control panels.
- Versatile 3-in-1 Integration: Acts as a manual motor controller, disconnect, and overload protector, saving significant DIN rail space.
- Phase Failure Sensitivity: Advanced detection mechanisms protect against unbalanced loads and phase loss to prevent winding damage.
- Atmospheric Resilience: Features ambient temperature compensation up to 140°F, crucial for high-load starter combinations.
- Global Standards Compliance: Rated for 690V and carries IEC, UL, CSA, and ATEX certifications for international compatibility.
Is the 3RV2021-1CA10 a direct replacement for older Siemens parts?
Yes, this modern SIRIUS 3RV2 unit is the certified successor to the legacy 3RV1021-1CA10 series and integrates easily into existing 3RT2 contactor lineups.
What is the magnetic trip setting on this specific model?
This breaker features a fixed magnetic trip (N-release) at 33 A, which is approximately 13 times the maximum FLA current setting, providing robust short-circuit protection.
Can I add auxiliary signaling to this circuit breaker?
Definitely. The modular design supports front or side-mounted auxiliary contacts and signaling switches (like the 3RV29 series) to provide remote status feedback to your PLC or control circuit.
