The 3VA1080-2ED36-0BH0: Rated continuous current Iu is 80 A, with minimal thermal derating up to 50 °C (still 80 A); at 55 °C it drops to 76.8 A, and at 70 °C to 72 A. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard 3-pole MCCB panel cutouts.
Submit an RFQ through this listing. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.
The 3VA1010-2ED32-0JA0 is a smaller-frame sibling in the same SENTRON 3VA family — lower current rating (32 A) and different trip curve, but the same 3-pole line-protection architecture and undervoltage release option. Panel cutout dimensions differ; verify footprint before substituting.
Not without checking the cutout. The 3VA1080 frame is physically larger (130 × 76.2 × 70 mm vs the 3VA1010's smaller footprint), so the panel cutout and busbar spacing must be verified. Wiring terminals are similar but current rating differs — 80 A vs 32 A — so conductor sizing may also need review.
Siemens SENTRON MCCBs are designed to meet IEC 60947-2 and UL 489 standards. RoHS and REACH declarations are typically available from the manufacturer's support portal. The reference code per DIN EN 81346-2 is Q.
