No ground-fault detection here, so plan for a separate ground-fault relay if that's required. The 3-pole design handles the three-phase main circuit; spring-loaded terminals on both main and auxiliary circuits accept 0.25–2.5 mm² solid or 0.25–1.5 mm² finely stranded with ferrules. Dimensions are 45 mm wide, 90 mm high, 81 mm deep — zero clearance needed at the sides or rear. At 690 V AC it drops to 2 kA — that's the limit for 690 V systems; above that voltage, coordination with upstream protection is essential. For typical 400 V distribution panels, the 100 kA rating gives plenty of headroom for high-fault installations. ## Power Loss and Duty Cycle Total power loss in hot operating state is 7.25 W, with 2.4 W per pole. That's modest — no special ventilation needed in a standard enclosure. Maximum operating frequency at AC-3 duty is 15 operations per hour, which suits typical motor start cycles for pumps, fans, and conveyors. For higher cycling applications like rapid reversing drives, consider a contactor with a higher rated frequency.","metaTitle":"Siemens 3RV1011-1AA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1011-1AA20 SIRIUS motor protection circuit breaker, 1.6 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V.

The key difference is the continuous current rating: 1.6 A on the 1AA20 versus 1.0 A on the 1AA15. If the motor load is ≤1.0 A, the 1AA15 is the correct fit; for loads up to 1.6 A, the 1AA20 works.
