Product Overview

The Siemens 3RV2031-4PA10 is a SIRIUS 3RV2 series circuit-breaker sized S2 with a Class 10 thermal overload release adjustable from 28 to 36 A, and an instantaneous N-release set at 520 A. It protects three-phase AC motors by combining thermal and magnetic trip functionality, providing motor protection and overload/short-circuit clearing. It is typically used in industrial motor control panels for pump, fan, compressor, or conveyor protection. The part number (3RV2031-4PA10) identifies this specific trip class and current range.
