63 A MCCB with 242 kA interrupting — what that means for your panel
The headline number here is the interrupting capacity: 242 kA at 240 V AC, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V.
Thermal derating and trip unit — the real selection data
Above that, it derates linearly: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C.
Physical fit — dimensions and panel integration
The 86 mm depth means it clears most standard enclosure depths without needing a protruding cover. Mounts via screw terminals to a backplate or DIN rail adapter; the SENTRON series uses a common accessory set (busbar connectors, shunt trips, auxiliary contacts) across the 3VA2 family.
