Siemens 3RV2011-1AA10 is a 3-pole motor protection circuit breaker from the SIRIUS 3RV2 series. The following provides detailed textual parameter descriptions: Basic Attributes Siemens 3RV2011-1AA10 belongs to the SIRIUS 3RV2 series of motor protection circuit breakers, with 3 poles, size specification S00, and dimensions (width × height × depth) of 45×97×91mm. It adopts standard DIN rail installation, with no restrictions on installation location, and has an IP20 protection level. It can display the switch status through the operating handle. The wiring uses top and bottom screw terminals, with the main circuit wiring terminal thread specification being M3, a tightening torque range of 0.8-1.2N·m, and compatible wire cross-sections of solid or stranded wire 0.75-2.5mm², multi-strand fine stranded wire 0.5-1.5mm². Its operating temperature range is -20°C to +60°C, storage and transportation temperature is -50°C to +80°C, and relative humidity during operation is 10%-95%.
Electrical Performance: The circuit breaker has a rated operating voltage of 690VAC, a rated frequency of 50/60Hz, an overload protection current setting range of 1.1-1.6A, and an instantaneous short-circuit release response current of 21A. Its short-circuit breaking capacity can reach 100kA at voltages of 240V, 400V, 500V, and 690VAC. The utilization category is AC-3, suitable for direct starting and stopping of three-phase asynchronous motors. The tripping level complies with Class 10 of the IEC 60947-4-1 standard, featuring phase loss protection and temperature compensation functions to effectively handle common faults during motor operation. Under UL/CSA certification standards, the full-load current rating of three-phase AC motors is 1.6A at both 480V and 600V.
The mechanical lifespan (B10 value, high demand rate, compliant with SN 31920 standard) is 50,000 cycles, and the proportion of dangerous failures (low/high demand rate, compliant with SN 31920 standard) is 40%. Regarding insulation distance, at 690V, the downward and upward distances to ground components are both 50mm, and the side distance is 30mm; at 500V, the downward and upward distances for live parts are both 30mm, and the side distance is 9mm. The product has passed UL/CSA certification, complies with RoHS standards, and meets relevant safety and environmental protection requirements.
