Siemens 3RV1021-0AA10-ZW97 — 0.16 A Motor Circuit Breaker, Class 10, 100 kA
The Siemens SIRIUS 3RV1021-0AA10-ZW97 is a 3-pole motor protection circuit breaker rated for 0.16 A continuous current with Trip Class 10 thermal overload characteristic. It delivers 100 kA breaking capacity across 240 V to 690 V AC, meaning it safely clears fault currents up to that level without upstream fuses needing to coordinate — a genuine high-fault rating for a 0.16 A device, so it holds its own even on high-capacity distribution panels.
DIN Rail Mounting & Panel Integration
Dimensions are 96 mm deep by 45 mm wide by 97 mm high — fits a standard 45 mm-wide DIN slot with 0 mm clearance needed at the side or rear. Mounting position is any orientation, so it works in vertical or horizontal panel layouts without derating. Terminal capacity accepts 2x (1... 2.5 mm²) solid or stranded, and 2x (2.5... 6 mm²) solid or stranded — covers common motor feeder cable sizes up to 6 mm². AWG equivalent is 2x (14... 10).
Shock resistance rated at 25g for 11 ms. Substance prohibitance date of 01.05.2012 aligns with RoHS compliance. The product extension supports an auxiliary switch (sold separately).
