Motor Protection Circuit Breaker for 0.55 kW Loads
The Siemens SIRIUS 3RV1011-1AA15-0BA0 is a motor protection circuit breaker rated for 1.6 A continuous current, sized for a 0.55 kW motor at 400 V AC.
DIN Rail Mounting and Panel Fit
The 45 mm wide, 90 mm tall, 81 mm deep footprint fits a standard 4-module width on the rail, leaving room for a contactor and overload relay in a motor starter lineup. Any mounting position is permitted, so vertical or horizontal rail orientation works. Screw-type terminals on both main and auxiliary circuits accept solid conductors: 2× (0.5…1.5 mm²) and 2× (0.75…2.5 mm²), or stranded equivalents. AWG equivalents for main contacts are 2× (18…14). Zero clearance required at the sides or rear for heat dissipation.
Breaking capacity holds at 100 kA across 240 V, 400 V, and 500 V AC, then drops to 2 kA at 690 V AC.
Shock rated at 25g for 11 ms. RoHS compliance is documented with a substance prohibition date of 01/01/2013.
