Line protection MCCB with thermal-magnetic release
The rated continuous current Iu holds at 63 A from 40 °C through 50 °C, then derates to 60.48 A at 55 °C and 56.7 A at 70 °C — the thermal curve governs the actual ampacity in a warm panel, not the 63 A nameplate. Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. At 415 V the 32 kA figure covers most European industrial distribution panels; the 690 V rating of 7.5 kA is the limiting case for 690 V line-side faults.
The 3VA1063-2ED36-0KC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.
