The Siemens 3RV6011-1FA10 is a SIRIUS motor protection circuit breaker in size S00, designed for protecting three-phase induction motors against overload and short circuit. It is rated for a 5 A operational current in AC-3 duty at 400 V, with a Class 10 trip characteristic that matches standard motor startup profiles — the thermal overload release lets the motor accelerate without nuisance tripping, while the magnetic short-circuit trip clears faults fast.
What the Ratings Mean for Fit
The 5 A rated current at AC-3 / 400 V is the motor-load rating — it governs what size motor this breaker protects. For a standard 400 V four-pole induction motor, 5 A typically corresponds to a 2.2 kW output. The Class 10 trip means the thermal element will not trip in under 10 seconds at 7.2× the current setting, which is sufficient for most direct-on-line starts. The 690 V rated insulation voltage gives headroom if the line voltage is 480 V or 600 V class. The 3-pole construction is standard for three-phase motor circuits.
Panel Integration & Mounting
Mounts via screw fixing or snap-on onto 35 mm DIN rail per DIN EN 60715. The S00 frame is the smallest in the SIRIUS 3RV6 family: 45 mm wide, 97 mm tall, 96 mm deep. Any mounting position is allowed. Clearance: 50 mm above and below the breaker, 30 mm to the sides, 0 mm forward and backward. Screw terminals accept 2× (0.75 to 2.5 mm²) solid/stranded or 2× 4 mm², torque 0.8 to 1.2 N·m.
Environmental & Compliance
Operating temperature range -20 to +60 °C, transport/storage -50 to +80 °C. Relative humidity 10 to 95 % during operation. Shock resistance 25 g / 11 ms per IEC 60068-2-27. Installation altitude up to 2 000 m. RoHS compliance date 05/01/2012 — the part is RoHS-compliant.
