Breaking capacity is 100 kA at 400 V AC and holds that rating up to 500 V AC, dropping to 6 kA at 690 V AC — so in most 400 V industrial panels this breaker clears faults without cascading upstream. ## Trip Class and Motor Protection Ground fault detection is not included — that requires an external module or upstream RCD. Rated operational voltage for AC-3 duty is 690 V maximum, and the unit dissipates 7.25 W total (2.4 W per pole) in hot operating state — factor that into enclosure thermal calculations if panel is tightly packed. ## Termination and Integration Screw-type terminals on both main and auxiliary circuits accept 2x (1... 2.5 mm²) solid or stranded, or 2x (2.5... 6 mm²) — covers most panel wiring up to 6 mm² without lugging. The auxiliary switch slot is populated, so you get a signal contact for PLC feedback or status indication without an add-on block. Shock resistance rated at 25g for 11 ms. Substance prohibitance date of 01.05.2012 aligns with RoHS compliance — the part meets EU substance restrictions effective from that date.","metaTitle":"Siemens 3RV1021-1EA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1EA10-ZW97 motor protection circuit breaker, 4 A continuous, CLASS 10 trip, 100 kA breaking at 400 V.
