Breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V AC — the high 100 kA figure at common distribution voltages (400 V) means this breaker can be used in high-fault-current panels without needing a current-limiting upstream device, simplifying selectivity coordination. ## Integration Notes Depth is 96 mm, height 97 mm — the 96 mm depth is within the standard 100 mm deep enclosure profile, so it clears most shallow gland plates without a spacer. No ground-fault detection on this variant; if GF is required, specify the -Z suffix options or an external module. Screw terminals on both main and auxiliary circuits; main terminals accept 2×(1…2.5 mm²) or 2×(2.5…6 mm²) solid/stranded — double-ferrule terminations are fine. The auxiliary switch option is available but this specific order code ships without auxiliary contacts (0 CO,). Rated operational voltage is 690 V AC, with an AC-3 motor switching rating of 4 A at 400 V and a maximum operating frequency of 15 operations per hour — sized for occasional motor starts, not high-duty cycling.","metaTitle":"Siemens 3RV1021-1EA10-0FJ0-ZX95 SIRIUS Motor Protection CB,","metaDescription":"Siemens SIRIUS 3RV1021-1EA10-0FJ0-ZX95 motor protection circuit breaker, 4 A rated, Class 10 trip, 100 kA breaking at 400 V.
