Breaking capacity varies with system voltage: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. These are the values for the 3VA2110-5JQ32-0JC0 per the datasheet — the 4.25 kA figure at 690 V is the limit that governs any 690 V application, not a higher value from a different variant. For selectivity coordination studies, use these published figures rather than a generic family curve.
At 55 °C it derates to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A. Maximum power loss is 10 W.
