Siemens Industrial Controls 3RV2021-1JA10 Protector
The Siemens 3RV2021-1JA10 Protector is a high-performance motor starter protector engineered for the thermal and magnetic protection of three-phase motors. This SIRIUS innovation series unit features a current adjustment range of 7-10 AMP, utilizing a Class 10 overload trip profile to disconnect power in 10 seconds or less during overcurrent conditions. Designed for versatile integration, this Type E self-protected combination motor controller facilitates motor control, disconnect, and short-circuit protection within a single compact Size S0 frame. For contractors requiring reliable branch circuit protection, this device offers a screw terminal connection and mounts directly onto standard 35mm DIN rails. It is phase loss sensitive, ensuring the safety of windings in the event of a single-phasing fault. With a rated operational voltage of 690V and a robust rotary handle for clear ON/OFF and trip indication, the 3RV2021-1JA10 provides a streamlined solution for heavy-duty industrial motor protection and system reliability.
Key Benefits- Enhanced Safety: Built-in phase loss sensitivity and thermal-magnetic trip mechanisms provide comprehensive protection against motor failure.
- Space Efficiency: Combines multiple functions into a single Size S0 housing, reducing the footprint in electrical control panels.
- Reliable Trip Characteristics: Incorporates Class 10 tripping to safeguard motors during high-load starting and sustained overloads.
- Type E Approval: Functions as a self-protected combination motor controller, eliminating the need for separate fuses or circuit breakers upstream in specific applications.
- Ease of Integration: Features standard screw terminals and 35mm DIN rail mounting for rapid installation and compatibility with the SIRIUS modular system.
Is the 3RV2021-1JA10 compatible with auxiliary switches?
Yes, this unit is designed to accept front or side-mounted auxiliary contacts, such as the 3RV2901 series, for signaling and remote status monitoring.
What is the maximum voltage rating for this motor protector?
This device carries a rated operational voltage of 690 V AC, making it suitable for a wide range of industrial power systems.
Can I use this for single-phase motor protection?
While designed primarily for three-phase systems, it can protect single-phase motors when current is routed through all three poles in series to maintain proper thermal balance and avoid nuisance tripping from the phase-loss sensitivty feature.
