The IP20 front protection means the operator side is finger-safe, but the terminals are live when the breaker is on, so panel builders should treat the wiring compartment as exposed. Breaking capacity is 100 kA at 400 V AC and also at 240 V and 500 V AC, dropping to 6 kA at 690 V AC. The AC-3 rated voltage max is 690 V, so it can switch motor loads on 400 V or 480 V systems with headroom. No ground fault detection, so that function must come from a separate module or upstream RCD. The auxiliary switch extension is available for remote status feedback; the screw-type terminals on both main and auxiliary circuits accept solid or stranded wire from 1 to 6 mm² (2x per terminal) or AWG 14–10, which covers most panel wiring up to the 5 A rating. RoHS compliance date is 01.05.2012, which covers the current EU RoHS directive. Shock resistance is 25 g for 11 ms, adequate for standard industrial panel vibration.","metaTitle":"Siemens 3RV1021-1FA10-ZW96 SIRIUS Motor Protection Breaker,","metaDescription":"Siemens 3RV1021-1FA10-ZW96 SIRIUS motor protection circuit breaker, 5 A rated current, Class 10 trip, 100 kA breaking at 400 V.
