The Siemens 3RV6011-0FA10 is a SIRIUS size S00 motor protection circuit breaker, designed for a 0.5 A rated operational current at 400 V AC-3 duty — that is the motor full-load current it protects, not a bus rating. The magnetic short-circuit trip acts instantaneously on a fault, and the breaker itself is rated for a 690 V maximum operating voltage across 50/60 Hz mains.
The S00 frame occupies 45 mm width, 97 mm height, and 96 mm depth — a compact footprint that leaves 50 mm clearance above and below, 30 mm to the sides, and zero forward/backward clearance required, so it packs tightly into a motor control centre sub-panel. Screw-type terminals on the main circuit accept up to 2× 4 mm² solid or stranded, torqued to 0.8–1.2 N·m.
Environmental and mechanical tolerance
Rated for operation from -20 to +60 °C with 10–95 % relative humidity, and transport down to -50 °C. Withstands 25 g shock for 11 ms per IEC 60068-2-27, and installation altitude is allowed up to 2 000 m above sea level — figures that cover most industrial enclosures and unpressurised plant rooms without derating.
