At 240 V it rises to 100 kA; at 500 V it drops to 10 kA, and at 690 V to 4 kA. Any orientation works. The 45 mm wide footprint matches the standard SIRIUS 3RV1 compact frame — it'll drop into the same DIN-rail slot as the 3RV6021-4DA10 without panel rework. Screw terminals on both main and auxiliary circuits; accepts 1–2.5 mm² solid or stranded, or 2.5–6 mm² on the larger clamping range. Strip length is the usual 8–10 mm for this terminal family. Front face is IP20 — finger-safe but not washdown-rated. Shock-rated to 25 g at 11 ms, which is enough for most conveyor and machine-tool applications. Mechanical life is 100,000 operations typical on the main contacts.","metaTitle":"Siemens 3RV1021-4DA10-ZI41W96 SIRIUS Motor Protection Circui","metaDescription":"Siemens SIRIUS 3RV1021-4DA10-ZI41W96 motor protection circuit breaker. 25 A continuous, 11 kW at 400 V AC-3, Trip Class 10. 50 kA breaking capacity.
