Any mounting position is permitted. The enclosure dimensions are 149 mm deep, 75 mm wide, and 140 mm high — a standard SIRIUS frame that fits alongside other 3RV2 components in a motor control center. ## Clearance and spacing requirements At 400 V, the required clearance is 160 mm — this is the arc-flash boundary for safe operation, not the physical gap to the next device. At 240 V no clearance is required. Terminals accept 2x (1 to 35 mm²) or 1x (1 to 50 mm²) solid or stranded copper. Strip length per standard practice — the datasheet specifies the range. ## Environmental and operating limits Storage and transport range extends from -50 to +80 °C. The rated voltage range is 20 to 690 V. Maximum switching frequency under AC-3 duty is 15 operations per hour. The part is rated for 22 kW at 230 V and 25 hp at 220/230 V, per the listed power ratings.","metaTitle":"Siemens 3RV2131-4KA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV2131-4KA10 motor protection circuit breaker, CLASS 10 trip, 30 kA breaking capacity at 400 V.
