This MCCB's interrupting rating varies sharply with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. At 690 V the 17 kA rating is still adequate for many motor-control centers, but verify against the transformer's short-circuit capacity before specifying.
The 200 A rating holds flat from 40 °C through 50 °C ambient; above that it derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If the breaker is enclosed in a non-ventilated panel or stacked tightly with other heat sources, use the 60 °C or 65 °C column for your continuous-current budget.
Physical fit and mounting
No trip indicator is fitted, so fault diagnostics rely on the undervoltage release status or an external indication circuit.
