Rated continuous current is 0.25 A, with a CLASS 10 trip characteristic — meaning it will trip within 10 seconds at 7.2× rated current, matching the thermal curve of standard squirrel-cage induction motors during start-up. Ground fault detection is not included — that requires a separate residual-current device or a different SIRIUS variant. Main circuit terminals are spring-loaded, accepting 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) fine-stranded with ferrule. The auxiliary switch option allows a separate signal contact for remote status. Shock resistance is 25g for 11 ms, and mechanical endurance of the main contacts is rated at 100,000 operations. Maximum switching frequency at AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1011-0CA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-0CA20-ZX95 SIRIUS motor protection circuit breaker, 0.25 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.
