That 16 A at AC-3 duty (400 V) means it directly protects a motor drawing that full-load current; the 7 W typical power loss tells you it's not a power hog in a crowded panel. The S0 frame footprint is 45 mm wide by 97 mm tall by 96 mm deep. That 0 mm forward clearance means it can sit flush against a panel door or busbar cover without extra breathing. Screw-type terminals on top and bottom accept 2×(1…2.5 mm²) solid/stranded or 2×(2.5…10 mm²) — torque to 2…2.5 N·m. Rated 16 A at AC-3 (400 V) — that's the motor-switching current, not a resistive load. Shock-rated to 25 g / 11 ms per IEC 60068-2-27, so it holds up in mobile or high-vibration installations. Operating temperature -20 to +60 °C, 10-95% RH non-condensing.","metaTitle":"Siemens 3RV6021-4AA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV6021-4AA10 SIRIUS motor protection circuit breaker, 16 A rated, Class 10 thermal-magnetic trip, 3-pole, 690 V, screw terminals.

The difference is the release setting: the 4AA10 is a fixed 16 A thermal-magnetic; the 4DA10 has a different fixed rating. If the panel was wired for the 4DA10's rating, the 4AA10 will physically fit and mount, but the protection curve must match the motor FLA — verify the current rating before swapping."},{"question":"What is the depth of the 3RV6021-4AA10?","answer":"96 mm depth on the S0 frame, with zero forwards or backwards clearance required."},{"question":"What compliance documentation does Siemens provide for this part?","answer":"The part carries RoHS compliance with a substance prohibition date of 05/01/2012.
