What this 63 A MCCB carries
The interrupting ratings climb to 121 kA at 240 V and 75.6 kA at 415 V, so it handles high-fault panels without cascading upstream.
Thermal derating at elevated ambient
Above that it derates stepwise: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
The 4-pole footprint fits standard SENTRON panel cutouts. The shunt trip (STL) release is included; the integrated auxiliary trip is order code 3VA9688-0BL30. No N-conductor protection — this is a straight line-protection device without neutral monitoring.
