63 A MCCB with voltage-graded interrupting ratings
Per the datasheet, the current holds flat at 63 A through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — so the full rating is available across most panel interior temperatures without a derate factor. Breaking capacity varies by system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. At 690 V the 7.5 kA rating limits application to lower-fault installations.
The 3-pole footprint fits standard MCCB panel cutouts and DIN-rail adapter plates. The 17.3 W power loss at full load should be factored into enclosure thermal calculations, especially in sealed cabinets.
