Any mounting position allowed. The 55 mm width fits standard panel layouts; depth is 149 mm, height 140 mm. Finger-safe touch protection on the front (IP20) means it can sit in open-back enclosures without additional shrouding. Main circuit terminals are screw-type with box terminals. Accepts 2x (0.75... 16 mm²) solid or 2x (0.75... 25 mm²) stranded, plus a single 0.75 … 35 mm² stranded. AWG equivalents: 2x (18... 2) solid, 1x (18... 2). Auxiliary and control circuits also use screw terminals. Fine-stranded with core-end processing: 2x (0.75... 16 mm²) or 0.75... 25 mm². Power dissipation at AC in hot operating state is 19 W total, 6.3 W per pole. Plan for that heat load in dense panel layouts — the 55 mm width leaves some air gap between adjacent breakers, but derating may apply above 40 °C ambient. Shock resistance 25 g / 11 ms. Substance prohibitance date 07/01/2006 — this part complies with RoHS-style restrictions from that date. Surge voltage resistance rated 6 000 V.","metaTitle":"Siemens 3RV1431-4EA10-0BA0 SIRIUS Circuit Breaker, 32 A, CLA","metaDescription":"Siemens SIRIUS 3RV1431-4EA10-0BA0 circuit breaker for transformer protection. 32 A continuous, CLASS 10 trip, 50 kA at 400 V.
