Mounting position is any orientation, so vertical or horizontal rail layouts both work. Main circuit terminals 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 the main contacts are 2x (14…10). Auxiliary and control circuits use separate screw-type terminals. Clearance: zero mm backwards and zero mm at the side — no extra air gap needed between adjacent devices on the rail. Rated short-circuit breaking capacity varies by line voltage: 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC (–). The auxiliary switch is transverse-design and field-installable. Panel wiring practices differ — if your shop standardizes on spring-cage, the 3RV6021-4DA10 is the closer fit without retraining the wire prep. RoHS compliance date is 01.05.2012 — the part meets the EU RoHS substance restrictions effective from that date.","metaTitle":"Siemens 3RV1021-4DA15-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-4DA15-ZW97 motor protection circuit breaker, 25 A continuous, CLASS 10 trip, 50 kA at 400 V.
