The Siemens SIRIUS 3RV6011-0HA10 is a 3-pole motor protection circuit breaker in the S00 frame size, rated at 0.8 A operational current (AC-3 at 400 V) with a Class 10 trip characteristic. It protects motors against overload and short-circuit in a single device, combining a thermal overload release with a magnetic short-circuit trip.
The 0.8 A rated current at AC-3 duty (400 V) means this breaker is sized for small motor loads — fractional-horsepower pumps, fans, or conveyor drives drawing under an amp. Class 10 trip ensures it holds in during a standard motor start (typically under 10 seconds) but trips fast on a stalled rotor, protecting the winding from thermal damage. The 690 V maximum rated insulation voltage gives headroom for 400 V line-to-line systems with margin.
No REACH or UL listing appears in the evidence, but the IEC design and CE marking are standard for this class.
Integration note
Screw-type terminals on top and bottom accept 2x (0.75 to 2.5 mm²) solid/stranded or 2x 4 mm², with a tightening torque of 0.8 to 1.2 N·m.
