Motor power assignments are 18.5 kW at 230 V, 50 hp at 460/480 V, and 62 A at 600 V, so it covers a 50 hp motor on a 480 V North American supply or an 18.5 kW European-rated motor at 230 V. ## Trip class and protection logic Ground fault detection is not included — if that's required, you'd add a separate ground-fault relay or choose a variant with that feature. Dimensions are 55 mm wide, 140 mm tall, 149 mm deep — the 55 mm width is a standard 3-module footprint on a DIN rail, so it occupies three 18 mm slots. Main circuit terminals accept 2×(1–35 mm²) or 1×(1–50 mm²) solid or stranded copper, with M6 screw terminals.","metaTitle":"Siemens 3RV2031-4JA10-ZW96 SIRIUS Motor Protection CB, 65A,","metaDescription":"Siemens SIRIUS 3RV2031-4JA10-ZW96 motor protection circuit breaker, 65 A rated at 480 V, 30 kA breaking capacity at 400 V, CLASS 10 trip.
