Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V — that's the fault current it can safely interrupt without welding contacts or venting plasma into the panel.
Full 125 A rating holds through 50 °C ambient. Above that it derates linearly: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C.
Sourced through independent distribution; quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
Breaking capacity is 52.5 kA at 415 V.
Both are 3-pole SENTRON MCCBs with similar dimensions, but the 3VA1110-5ED36-0AC0 is a different frame size with different trip characteristics. Panel cutout and busbar spacing may match, but verify the trip unit and current rating against your coordination study before swapping.
