Rated for a voltage range of 20 to 690 V, the interrupting capacity is backed by gL/gG fuse coordination: 50 A at 400 V, 40 A at 500 V, and 35 A at 690 V. This tells you the maximum fuse size the breaker can coordinate with at those voltage levels — critical for selective coordination in a distribution panel. Physical footprint: 45 mm wide, 106 mm high, 97 mm deep. Minimum clearance to adjacent devices: 50 mm upward and downward, 30 mm to the side, zero forward and backward. That zero backward clearance means it can sit flush against a backplate or panel door without derating — useful when packing multiple breakers into a shallow enclosure. ## Fault detection and switching performance Includes phase failure detection but no ground fault detection. Maximum switching frequency under AC-3 and AC-3e duty is 15 operations per hour — this is a protection device, not a contactor for frequent cycling. The motor ratings at various voltages (0.5 hp at 230 V, 1.5 hp at 220/230 V, 3 hp at 460/480 V, 5 hp at 575/600 V) give you the load-side capability for direct motor protection.","metaTitle":"Siemens 3RV2411-1GA20 SIRIUS Circuit Breaker, Class 10, 50 A","metaDescription":"Siemens 3RV2411-1GA20 SIRIUS circuit breaker for transformer protection.
