Breaking capacity is 100 kA across the full AC voltage range (240 V through 690 V), so it safely interrupts high fault currents without cascading to upstream devices. Dimensions: 45 mm wide, 97 mm high, 96 mm deep — fits standard control-panel layouts with no side clearance required. IP20 protection on the front allows installation in enclosed panels where no water ingress is expected. Screw-type terminals on main and auxiliary circuits accept solid conductors 2x (0.5–1.5 mm²) and 2x (0.75–2.5 mm²), or stranded 2x (1–2.5 mm²) and 2x (2.5–6 mm²). AWG equivalents for main contacts: 2x (14–10). The SIRIUS series includes other motor protection breakers with different current ratings (e.g., 3RV1011-0HA10, 3RV1011-0GA10, 3RV2021-1FA15), but the 3RV1021-0JA15 is the 1 A Class 10 variant with 100 kA breaking capacity. Shock resistance: 25g / 11 ms. The part carries a substance prohibitance date of 01.05.2012, indicating RoHS/REACH compliance as of that date.","metaTitle":"Siemens 3RV1021-0JA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-0JA15 SIRIUS motor protection circuit breaker, rated 1 A continuous, Trip Class 10, 100 kA breaking capacity at 400 V.
