Above that, the TM210 release starts to pull back: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C. The thermal curve is the binding limit, not the nameplate.
Dimensions are 70 mm deep, 50.8 mm wide, 130 mm tall — a standard 2-pole MCCB footprint for DIN-rail or screw-mount panel assembly. Front IP40 protection means it's splash-safe from the front but not sealed for washdown; keep it inside the enclosure.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Both are 2-pole SENTRON MCCBs with the same physical footprint (70 mm depth, 50.8 mm width, 130 mm height) and the same 125 A rating at 40 °C, so they share the same mounting and bus-bar pattern. The difference is the overcurrent release design — this one uses TM210; the 5EE32 variant uses a different release. Check the release curve against your coordination study before swapping.
The SENTRON 3VA series typically carries UL, CSA, IEC 60947-2, and CE marking. Specific documentation (RoHS, REACH, Declaration of Conformity) is available from Siemens upon request or through their support portal.
