Siemens Industrial Controls 3RV2021-1HA10 Protector
The Siemens 3RV2021-1HA10 Protector is a heavy-duty SIRIUS 3RV2 motor starter protector designed for professional-grade motor protection in industrial and HVACR environments. This Size S0 manual motor starter handles currents from 5.5A to 8A, offering precise Class 10 thermal overload protection to prevent motor burnout during stalling or overload conditions. Engineered for short-circuit protection, the unit features a high breaking capacity of up to 65kA at 480V, ensuring the safety of downstream components and minimizing downtime in the event of a fault. The integrated phase loss sensitivity provides an extra layer of security, detecting unbalanced loads before they cause critical damage. With a robust rotary handle for clear ON/OFF/TRIP status and standard screw-terminal connections, this IEC-rated motor controller is optimized for 35mm DIN rail mounting, allowing for high-density side-by-side installations in compact control panels while remaining ambient compensated up to 140°F.
Key Benefits- Multi-functional Design: Combines motor control, disconnect, short-circuit, and overload protection into a single UL-approved Type E self-protected combination motor controller.
- Enhanced Reliability: The thermal-magnetic trip mechanism and phase loss protection safeguard your 3-phase motors against the most common electrical failures.
- Simplified Installation: Standard S0 frame size and screw terminals allow for seamless integration with 3RT2 contactors and rapid cabinet wiring.
- Clear Diagnostics: The rotary actuator provides visible trip indication, helping technicians quickly identify faults and restore service.
Is this unit compatible with older Siemens MSPs?
Yes, the 3RV2021-1HA10 is the factory-recommended replacement for the obsolete 3RV1021-1HA10 series, offering improved performance in the same footprint.
Does this protector require a separate overload relay?
No. As a Manual Motor Protector (MMP), it contains internal bimetallic and magnetic trips, eliminating the need for a standalone overload relay in many applications.
Can I add auxiliary contacts to this device?
Absolutely. It is compatible with front-mounted or side-mounted SIRIUS auxiliary switches for remote signaling and status monitoring.
