Dimensions are 55 mm wide, 140 mm tall, 149 mm deep. The 55 mm width is a three-module footprint on the rail — plan for that slot count when laying out a multi-breaker panel. Any mounting position is acceptable. Screw-type terminals on the main circuit accept 2×(1–35 mm²) or 1×(1–50 mm²) solid or stranded copper. Torque spec for the M6 main contact screws — standard for this current class. The terminals are sized for the 52 A continuous rating at 480/600 V. ## Environmental range Temperature compensation is active across the full operating range. Rated voltage covers 20–690 V.","metaTitle":"Siemens 3RV2031-4WA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2031-4WA10-ZX95 SIRIUS motor protection circuit breaker.
