Description

The Siemens 3RV1031-4HA10 is a screw-type circuit breaker rated for 40–50 A thermal release and 650 A short-circuit release, optimized for motor protection applications (Class 10). Suitable for size S2 configurations, it features standard switching capacity and utilizes screw terminals for secure connections. Physical dimensions are compact, measuring 147 mm x 62 mm x 167 mm with a net weight of approximately 1.046 kg, ensuring efficient space utilization in industrial control panels.

 

Engineered to meet motor protection demands under Class 10 standards, the unit safeguards electrical systems against overloads and short circuits while maintaining reliable operation across varied industrial environments. Though phased out from production, this model remains supported through documentation downloads and direct compatibility with its successor—the Siemens SIRIUS series (preferred replacement: model number **3RV2031-4WA10**). Engineers sourcing replacements or upgrading installations can utilize Siemens' conversion tools to transition seamlessly.

 

This device adheres strictly to high-performance electrical safety parameters suitable for automated machinery systems demanding robust thermal-magnetic operation characteristics within specified current ratings and wiring configurations. Its consistent performance makes it a viable choice in legacy system maintenance or as a reference point during migration projects involving updated Siemens solutions.
