Siemens Industrial Controls 3RV2031-4PA10 Circuit breaker
The Siemens 3RV2031-4PA10 is a high-performance SIRIUS motor starter protector engineered for size S2 applications in demanding HVACR and industrial environments. This thermal-magnetic circuit breaker is optimized for protecting three-phase motors up to 30 HP at 460V, featuring a precise adjustment range of 28 to 36 Amps to match your specific motor FLA. Designed with Class 10 trip characteristics, it ensures reliable protection against overloads and phase loss, with an instantaneous magnetic release set at 520A for robust short-circuit mitigation. The unit supports 65kA switching capacity at 400V, making it a reliable choice for high-fault current installations. Integrated screw terminals provide secure, low-resistance connections for conductors up to 35mm², while the compact 55mm frame allows for maximum density on a standard 35mm DIN rail. This S2 manual motor starter is UL-listed for Type E self-protected combination motor controllers when used with appropriate terminal adaptors, simplifying your load feeder design and improving cabinet energy efficiency.
Key Benefits- Precise FLA Tuning: Rotary adjustment dial allows for exact setting between 28-36A, ensuring the motor protection circuit breaker aligns perfectly with nameplate ratings.
- Integrated Protection: Combines disconnect, short-circuit, and thermal overload protection in a single S2 frame, reducing wiring complexity and control cabinet footprint.
- Environmental Resilience: Ambient temperature compensation up to 140°F (60°C) prevents nuisance tripping in high-heat HVACR mechanical rooms.
- System Compatibility: Fully compatible with 3RT203 series contactors for building space-saving starter combinations.
- Visual Diagnostics: The rotary handle features a clear lockout position and visible trip indication to speed up troubleshooting for field technicians.
Is the 3RV2031-4PA10 suitable for single-phase applications?
Yes, though all three conducting paths must be wired in series to ensure the phase loss sensitivity and thermal trip elements function correctly for the single-phase load.
Does this unit require additional fuses for short-circuit protection?
Under many UL Type E applications, this Siemens SIRIUS circuit breaker acts as a self-protected unit. However, always verify current limiting requirements and your specific branch circuit protection rules for IT networks.
Can I add auxiliary switches to this motor protector?
Yes, the 3RV2 frame supports front-mount or side-mount 3RV29 auxiliary contacts for remote signaling or interlocking with other control components.
