At 11 W typical power loss, it won't cook adjacent devices in a densely packed panel. The 45 mm width (Size S0) and 96 mm depth fit standard enclosure backplates. Clearance: 50 mm upwards, 50 mm downwards, 30 mm at the side, 0 mm forwards, 0 mm backwards — so it can be stacked tight against the back panel or busbars. Screw-type terminals accept 2x (1…2.5 mm²) solid/stranded or 2x (2.5…10 mm²), with a tightening torque of 2…2.5 N·m. AWG equivalents: 2x (16…12) or 2x (14…8). Operates from -20 to +60 °C, transports from -50 to +80 °C, with 10…95 % relative humidity during operation. Installation altitude up to 2 000 m. Shock resistance: 25g / 11 ms per IEC 60068-2-27. Surge voltage resistance rated at 6 kV. RoHS compliance date: 05/01/2012. The part carries the SIRIUS brand designation for motor protection.","metaTitle":"Siemens 3RV6021-4NA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV6021-4NA10 SIRIUS motor protection circuit breaker, 28 A rated operational current, Class 10 trip, 690 V, Size S0.

The key difference is the rated operational current: 3RV6021-4NA10 is 28 A at AC-3, 400 V, while the 3RV6021-4DA10 is a different current rating within the same frame. If the motor load matches 28 A, the panel cutout and wiring will fit — but verify the overload setting matches the motor FLA before commissioning."},{"question":"What compliance documentation does Siemens provide for 3RV6021-4NA10?","answer":"RoHS compliance is dated 05/01/2012. The part is designed to IEC 60068-2-27 for shock resistance and carries a 6 kV surge voltage resistance rating.
