Rated at 20 A continuous at 480 V and 600 V, it handles motors up to 10 hp at 460/480 V, 15 hp at 575/600 V, and 5 hp at 220/230 V. No ground fault detection on this variant. The main circuit uses spring-loaded terminals. Lifecycle status is current production. This is an active catalog line, sourced through standard Siemens distribution. Panel integration: S0 frame width is 45 mm, depth 97 mm, height 119 mm. Clearance requirements are 50 mm upwards, 50 mm downwards, 30 mm at the side — tight for a 45 mm wide device, so adjacent components can sit close.","metaTitle":"Siemens 3RV2023-4BA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2023-4BA20 SIRIUS motor protection circuit breaker, S0 frame, Class 10 trip, 20 A at 480/600 V.
