The S0 frame footprint is 45 mm wide, 119 mm tall, and 97 mm deep, so it fits a standard 45 mm slot in a panel layout. Clearance requirements: 50 mm above and below, 30 mm to the side, zero forward or backward — tight enough for dense MCC buckets. The horsepower ratings across voltages (, –) let you match it to NEMA motors directly: 2 hp at 230 V, 8 hp at 460/480 V, 10 hp at 575/600 V.","metaTitle":"Siemens 3RV2023-1KA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2023-1KA20 SIRIUS motor protection circuit breaker, S0 frame, CLASS 10 trip, 5.5 kW at 400 V, spring terminals, DIN rail mount, phase failure detection.
