It delivers a 100 kA breaking capacity across the 240 V to 690 V range, so it can interrupt high fault currents without upstream fusing in most panel designs. The spring-loaded terminals on both main and auxiliary circuits accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule, which matches the wiring practice for control panels feeding motor starters. IP20 finger-safe front protection allows panel-front access without additional shrouding. Any mounting position is permitted, which simplifies layout in crowded enclosures. ## Protection and duty cycle Rated for 15 operations per hour at AC-3 duty, which covers frequent starting cycles on conveyors or pumps. Power dissipation is 5.5 W total (1.8 W per pole) at rated load in hot operating state; account for this heat in enclosure sizing.","metaTitle":"Siemens 3RV1011-0JA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1011-0JA20 SIRIUS motor protection circuit breaker, 1 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.
