Interrupting capability and thermal derating
Its interrupting rating reaches 220 kA at 240 V AC, dropping to 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so at typical 400 V distribution levels it clears faults up to 154 kA without cascading upstream. The TM240 thermal-magnetic overcurrent release handles the overload curve; the breaker carries its full 200 A from 40 °C through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. For a panel running at 50 °C ambient, you get the full 200 A; above that, size the load to the derated figure.
