Width is 45 mm, depth 96 mm, height 97 mm. Zero clearance needed at the sides or rear — 0 mm backwards, 0 mm at the side — so you can pack these tight on a DIN rail without derating for air gap. Accepts solid or stranded conductors: 2× (1…2.5 mm²) and 2× (2.5…6 mm²). For AWG, 2× (14…10). Fine-stranded with core-end processing is also supported at the same cross-sections. Strip length and torque spec are standard for this terminal class — no special tooling needed. This is a panel-interior device, not a field-mounted enclosure breaker. RoHS compliance date is 01.05.2012, so it meets the EU substance restrictions for current installations. No explicit REACH or UL statement in the spec record, but the SIRIUS series carries IEC and UL certification as a standard — verify the specific UL file number with the order desk if your panel requires a marked UL listing.","metaTitle":"Siemens 3RV1021-0EA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-0EA10-ZW97 motor protection circuit breaker, 0.4 A continuous current, Trip Class 10, 100 kA breaking capacity at 400 V.
