The Siemens SIRIUS 3RV1011-0GA15-0BA0 is a motor-protective circuit breaker designed for 0.63 A continuous current, rated at 0.18 kW at 400 V. It uses a thermal overload release and a magnetic short-circuit trip, with Trip Class 10 protection — meaning it will trip within 10 seconds at a cold start under locked-rotor conditions, matching typical IEC motor starting curves for small pumps, fans, and conveyors. Breaking capacity is 100 kA at 240 V through 690 V AC, so it can handle high-fault-current panels without cascading upstream. Phase failure detection is built in, which protects motors against single-phasing on three-phase lines. Mounts via screw or snap-on onto 35 mm DIN rail per EN 50022, fitting into standard control panels. Front protection is IP20, so safe for enclosed panels; the enclosure itself provides the required IP rating for the environment.
DIN Rail & Wiring
Width is 45 mm — one standard 9 mm module pitch — and depth is 81 mm, leaving clearance for wiring ducts and adjacent components. Height is 90 mm. Mounting position is any; no derating for side or top mounting. Main and auxiliary/control circuits use screw-type terminals. Solid and stranded wire: 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²). AWG equivalents: 2x (18... 14). No ground-fault detection; that is handled separately if needed.
Compliance & Environment
Substance prohibitance date is 01/01/2013, indicating RoHS compliance (EU RoHS 2011/65/EU). Operating temperature range is -50 to +60 °C; storage and transport range is -50 to +80 °C. Shock resistance: 25 g at 11 ms. Power dissipation at rated continuous current in hot state: 5.5 W.
