The AC-3 category means it is tested for switching squirrel-cage motors including starting, plugging, and inching duty. The magnetic trip at 2.6 A provides instantaneous short-circuit protection; it will clear a fault without waiting for the thermal element, which is critical for limiting let-through energy to the contactor. The 6 kV rated surge voltage resistance and 690 V insulation voltage at pollution degree 3 mean this breaker is suitable for 400 V line-to-line systems with a solidly grounded neutral, and can handle transient overvoltages common in industrial environments without flashover. The size S00 footprint — 45 mm wide, 97 mm tall, 96 mm deep — fits the standard S00 slot in a Siemens motor starter assembly. No clearance needed forward or backward. ## Integration note for panel builders Screw-type terminals on top and bottom for the main current circuit. Accepts 2x (0.75 to 2.5 mm²) solid or stranded, or 2x 4 mm². AWG equivalent: 2x (18 to 12) or 2x (20 to 16). Finely stranded with ferrule: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Torque the main contact screws to 0.8 to 1.2 N·m. Relative humidity 10 to 95%. Maximum operating altitude 2000 m above sea level. Shock resistance 25g for 11 ms per IEC 60068-2-27. Power loss 5 W typical.","metaTitle":"Siemens 3RV6311-0BC10 SIRIUS Circuit Breaker, 0.2 A, Size S0","metaDescription":"Siemens SIRIUS 3RV6311-0BC10 circuit breaker for starter combinations. 0.2 A rated current, 690 V AC-3, 3-pole, size S00.
