Dimensions 97 mm deep, 45 mm wide, 106 mm tall — the 45 mm width (3 module spaces) is standard for size S00 breakers, making panel layout and fill factor predictable. The screwdriver shaft diameter is 3 mm, tip size 3.0 x 0.5 mm — use a slim-profile driver to avoid damaging adjacent terminals in a dense row. ## Electrical ratings and duty Rated operational voltage spans 20 to 690 V. At 230 V it handles 0.1 kW motor load (AC-3 duty), and at 480 V and 600 V the rated current drops to 0.4 A — so for higher-voltage motor circuits, size the breaker to the motor FLA, not the voltage alone. Breaking capacity holds at 100 kA across 240 V, 400 V, 500 V, and 690 V AC, giving solid SCCR headroom for most industrial panel designs. Rated for 15 switching operations per hour at AC-3 and AC-3e maximum — sufficient for typical motor starting cycles in conveyor or pump duty. Mechanical endurance of the main contacts is 100,000 operations typical, so it outlasts many contactors in the same branch.","metaTitle":"Siemens SIRIUS 3RV2311-0EC20 Circuit Breaker, 100 kA at 400","metaDescription":"Siemens SIRIUS 3RV2311-0EC20 circuit breaker for starter combos, size S00, 100 kA breaking capacity at 400 V AC, screw and snap-on DIN rail mount.
