Breaking capacity hits 100 kA across the full voltage range — 240 V, 400 V, 500 V, and 690 V AC — so it safely interrupts fault currents up to that level without cascading upstream, even on high-SCCR panels. Rated motor power is 0.55 kW at 400 V AC-3 duty, which covers small pump, fan, and conveyor drives in a 400 V line. ## DIN-rail mounting and wiring Depth is 96 mm, height 97 mm, with 0 mm clearance required at the back and sides — it sits flush against the backplane, simplifying enclosure layout. Main and auxiliary circuits use screw-type terminals accepting 2x (1 to 2.5 mm²) solid or stranded, or 2x (2.5 to 6 mm²) — the larger cross-section handles the full 1.6 A load without derating, while the smaller pair accommodates daisy-chained control wiring. Shock resistance is 25 g for 11 ms, and surge voltage withstand is 6 000 V — figures that qualify it for industrial environments with frequent switching transients.","metaTitle":"Siemens 3RV1021-1AA10-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1AA10-ZW98 motor protection circuit breaker, 1.6 A rated current, CLASS 10 trip, 100 kA breaking capacity at 400 V.
