Siemens Industrial Controls 3RV2031-4JA10 Circuit breaker
The Siemens 3RV2031-4JA10 is a high-performance SIRIUS motor starter protector designed for heavy-duty HVACR and industrial motor applications. This size S2 circuit breaker provides comprehensive protection against overloads and short circuits, featuring a thermomagnetic trip unit with an adjustable current range of 54 to 65 Amps. Engineered for Type E self-protected combination motor controllers, it integrates the functions of a disconnect, short circuit protector, and manual motor starter within a single compact 55mm housing. This reduces cabinet space requirements and total component count for complex control panels. The 3RV2031-4JA10 is optimized for minimization of energy losses and reduced heat dissipation, ensuring reliable operation even in dense mounting configurations. Built with screw terminals for secure electrical connections, it supports a high switching capacity of 65 kA at 400V and is fully compatible with 3RT203 contactors for seamless load feeder integration.
Key Benefits for Contractors:- System Efficiency: Thermal-magnetic trip optimization reduces power loss and cabinet heating, potentially allowing for smaller cooling units.
- Multi-Function Integration: Approved for use as a manual motor starter, motor disconnect, and group installation protector, simplifying NEC compliance.
- Phase Loss Sensitivity: Built-in protection against single-phasing conditions ensures motor longevity in unstable power environments.
- Rugged Reliability: Rated for a mechanical and electrical life of 20,000 switching cycles with a standard breaking capacity of 65 kA.
- Easy Installation: Standard 35mm DIN rail mounting and intuitive rotary handle with clear trip indication and lockout capability.
Is a terminal adapter required for the 3RV2031-4JA10?
Yes, for S2 frame size protectors rated above 45A used in Type E applications, a type E terminal adapter is mandatory to meet UL clearance and creepage requirements.
Can this breaker be used for single-phase loads?
It is primarily designed for 3-phase motors; however, it can protect single-phase or DC loads if all three conducting paths are connected in series to ensure the overload trip functions correctly.
What is the short-circuit trip value for this unit?
The instantaneous magnetic overcurrent release (N-release) is fixed at 845 A, which is approximately 13 times the maximum FLA adjustment setting.
