No side clearance needed — 0 mm spacing to adjacent devices. Breaking capacity is 100 kA at 240 V, 400 V, 500 V, and 690 V AC — flat across the voltage range, so no derating needed for higher-voltage panels. Rated insulation voltage 690 V, surge voltage resistance 6 000 V. Operating frequency max 15 switching cycles per hour at AC-3 duty. Power dissipation 5.5 W in hot operating state (1.8 W per pole). Shock resistance 25g / 11 ms. Mounting position any. ## Compliance documentation RoHS compliance date listed as 01.05.2012, indicating the part meets EU RoHS substance restrictions. No specific UL or CSA listing is recorded in the source data, but as a Siemens SIRIUS industrial control component it typically carries IEC/EN 60947-4-1 certification for motor starters. For a specific project UL listing, verify the exact variant against the manufacturer's declaration.","metaTitle":"Siemens 3RV1021-0FA10-ZW96 SIRIUS Motor Protection Breaker,","metaDescription":"Siemens SIRIUS 3RV1021-0FA10-ZW96 motor protection circuit breaker rated 0.5 A continuous, 100 kA breaking capacity at 400 V AC, Trip Class 10.
