Motor protection circuit breaker, 0.16 A, CLASS 10
The Siemens SIRIUS 3RV1021-0AA10-ZX95 is a motor protection circuit breaker rated at 0.16 A continuous current with a CLASS 10 trip characteristic — meaning it will trip within 10 seconds at 7.2x overload, fast enough to protect standard induction motors from locked-rotor heating while allowing normal start-up inrush.
DIN rail mount, IP20 front, 45 mm wide
The 45 mm width and 97 mm height fit a standard 4-module slot in a distribution board; 96 mm depth leaves clearance behind a 120 mm deep enclosure door.
Screw-type terminals on the main circuit accept 2x solid or stranded conductors from 1 to 2.5 mm², or 2x from 2.5 to 6 mm² — fine for the 0.16 A rating, but the terminal range also covers larger wire for the 100 kA fault path. AWG equivalents are 2x 14–10. No auxiliary contacts built in (0 for auxiliary contacts), but the unit accepts an add-on auxiliary switch block if needed.
Operating conditions and environment
Shock resistance is 25g for 11 ms — survives most industrial vibration and transport handling. Mounting position is any orientation.
