Siemens Industrial Controls 3RV2031-4DB10 Circuit breaker
Optimize your motor protection with the Siemens 3RV2031-4DB10, a high-performance SIRIUS Motor Starter Protector specifically engineered for industrial HVACR and control applications. Built on the S2 frame size, this 3-pole circuit breaker handles a current rating of 18-25A, providing essential thermal-magnetic protection for load feeders. As a Class 20 device, it offers extended tripping delays suitable for motors with heavy starting loads or longer ramp-up times, ensuring the MSP S2 maintains operational continuity under demanding conditions. The unit is rated for an operational voltage of 690V and features a high short-circuit breaking capacity of 65kA, making it a reliable choice for motor protection circuit breakers in complex electrical infrastructures. The screw terminal design ensures a vibration-resistant, secure connection for field wiring, while the rotary handle provides clear ON/OFF/TRIP status at a glance. For contractors building Type E self-protected combination motor controllers, this unit integrates disconnect, short-circuit, and overload functions into a compact, 55mm-wide footprint.
Key Benefits:
- Adjustable Thermal Overload: Dial range of 18-25A allows for precise field matching to the motor's Full Load Amps (FLA).
- Heavy-Duty Trip Characteristic: Class 20 rating prevents nuisance tripping during longer starts common in high-inertia HVACR equipment.
- Integrated Phase Failure Sensitivity: Provides critical thermal-magnetic protection against single-phasing conditions that can lead to motor burnout.
- Direct Mount Compatibility: Seamlessly pairs with 3RT2 contactors via link modules to create space-saving, fuseless load feeders.
- Global Standards Compliance: Rated for use in UL/CSA, CE, and ATEX environments, supporting diverse international installations.
Common Questions:
What is the difference between Class 10 and Class 20 for this circuit breaker?
The Class 20 rating on this 3RV2031-4DB10 means it can withstand 600% of the set current for up to 20 seconds before tripping, compared to 10 seconds for Class 10. This makes it ideal for heavy-duty motors in refrigeration or ventilation that require more time to reach full speed.
Do I need a separate terminal block for UL Type E applications?
For S2 frame units like this one rated at 45A or less, the 3RV2031 series typically meets the required spacing for Type E combination motor controllers without additional terminal adaptors, though always verify local codes and specific enclosure requirements.
How do I reset the breaker after a trip event?
The rotary handle will move to a distinct "tripped" position. To reset, move the handle to the OFF position first to reset the internal mechanism, then back to ON. Always allow time for the thermal bimetal to cool before re-engaging.
