Breaking capacity is a solid 100 kA at 400 V AC, and it holds that same 100 kA at 240 V, 500 V, and 690 V AC. It includes phase failure detection, so if one phase drops out on a three-phase motor, the breaker trips before single-phasing cooks the winding. No ground fault detection on this unit — that's handled separately if needed. The 45 mm width means it takes up a single 45 mm slot on the rail — standard footprint for this class. Depth is 96 mm, height 97 mm. Zero clearance needed at the back or sides for heat dissipation, so you can pack breakers tight in a row. Accepts solid and stranded wire: 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) per terminal. AWG equivalents are 2x (14 to 10). That covers most control-panel wiring for a motor circuit of this size. IP20 on the front face — finger-safe from the panel front, but not washdown-rated. Shock rated at 25g for 11 ms, so it holds up in vibrating machinery. Substance prohibition date of 01.05.2012 aligns with RoHS compliance timelines.","metaTitle":"Siemens 3RV1021-0GA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV1021-0GA10 motor protection circuit breaker, 0.63 A continuous, Class 10 trip, 100 kA breaking capacity at 400 V.
