| Design Of The Product | for motor protection |
The Siemens 3RV1021-0HA10-ZW97 is a SIRIUS motor protection circuit breaker rated for 0.8 A continuous current with a 100 kA breaking capacity across 240 V to 690 V AC, making it suitable for high-fault-current industrial panels where a standard MCB would not hold.
Screw-type terminals on both main and auxiliary circuits accept 1–2.5 mm² solid or stranded (two conductors per clamp) and 2.5–6 mm² for larger feeds, so it handles mixed wire sizes common in retrofit panels.
Both are 45 mm wide, snap onto 35 mm DIN rail, and use screw terminals, so the mechanical fit is the same. The key difference is the continuous current rating: 0.8 A on this part versus the 3RV1011-0HA10's rating — verify the motor FLA before swapping.
The part carries a RoHS substance prohibition date of 01.05.2012, indicating compliance with EU RoHS. For UL, CSA, and IEC certifications, refer to the manufacturer's declaration or the product datasheet.
