At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. The rated insulation voltage Ui is 800 V, and the operating range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.
The 3-pole footprint is standard for a 63 A MCCB; it occupies three module widths on the rail. The auxiliary contact version is 2 switches HQ, which plug into the front accessory slot.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The 3VA1112-5EF32-0CA0 is a higher-current sibling in the same SENTRON 3VA family, but it carries a different frame size and interrupting rating — it won't drop into the same panel without checking the mounting footprint and bus bar spacing. Stick with the 3VA1063 for a direct fit.
Rated continuous current Iu is 63 A, with interrupting ratings of 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. It's a 3-pole MCCB with a TM210 thermal-magnetic release and an undervoltage release.
