Product details

The Siemens SIRIUS 3RV6311-1BC10 is a 3-pole circuit breaker sized for starter combinations, size S00. The magnetic instantaneous short-circuit trip responds at 26 A, per the datasheet.

The 45 mm width and 96 mm depth fit standard S00 footprint panels. Any mounting position is permitted. Clearance requirements: 50 mm upward, 50 mm downward, 30 mm at the side; no forward or backward clearance needed.

Electrical ratings and trip characteristics

Rated for 50/60 Hz operation. The magnetic short-circuit trip unit is non-adjustable, set at 26 A. This means the breaker will hold motor inrush without nuisance tripping but clears a fault above that threshold. Power loss is 6 W typical. Surge voltage withstand is 6 kV. Humidity tolerance 10 to 95%.

Lifecycle stage is current per the manufacturer. The part carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance from that date. Installation altitude maximum 2 000 m. Shock resistance 25g / 11 ms per IEC 60068-2-27.
