The Siemens 3RV6011-1HA15 is a SIRIUS motor protection circuit breaker — Size S00, 3-pole, rated 8 A with a Class 10 trip curve, meaning it clears overloads fast enough to protect standard induction motors during start-up without nuisance tripping. Rated operational current is 8 A at up to 690 V AC-3, switching frequency max 15 operations per hour, so it's sized for a typical small motor branch circuit — think conveyors, pumps, or fans in a control panel.
Mounts in any position on 35 mm DIN rail (screw or snap-on) per DIN EN 60715, with 45 mm width and 96 mm depth — fits standard S00 footprint in a motor control center or panel. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5 to 2.5 mm²) solid/stranded or 2x (18 to 12 AWG) for the mains, with a tightening torque of 0.8 to 1.2 N·m.
Rated for operation from -20 to +60 °C, 10 to 95% relative humidity, with a 6 kV surge voltage withstand — suitable for industrial control panels in unconditioned plant environments. Shock-resistant to 25 g / 11 ms per IEC 60068-2-27; RoHS compliance dated 05/01/2012.
