The breaker handles up to 690 V AC-3 (motor switching duty) at 50/60 Hz, making it suitable for 400 V and 480 V line supplies common in industrial panels. The 1.25 A rated operational current sets the motor full-load current the breaker is calibrated to protect — spec this for a motor drawing roughly 1.25 A or less at full load. The thermal overload release tracks motor heating; the magnetic short-circuit trip provides instantaneous magnetic protection on high faults. The Class 10 trip class is the standard for standard squirrel-cage motors; it clears a locked-rotor condition before the motor windings overheat. The 690 V maximum rating covers virtually all low-voltage industrial networks up to 600 V class. The 6 W typical power loss is low — no special ventilation required in a standard enclosure. Main and auxiliary circuits use screw-type terminals; accept 2×(0.5–1.5 mm²) solid/stranded or 2×(0.75–2.5 mm²), torque range 0.8–1.2 N·m. AWG equivalents: 2×(18–12) for main, 2×(20–16) for auxiliary.","metaTitle":"Siemens 3RV6011-0KA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV6011-0KA15 motor protection circuit breaker, 1.25 A rated operational current, Class 10 trip, 690 V, Size S00, screw-type terminals.
