The interrupting ratings climb to 187 kA at 240 V AC, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — figures that tell you this breaker can sit at the main or a high-fault subfeed without needing an upstream current-limiting fuse. That matters when you are coordinating with downstream breakers: you need to know the TM240's band, not guess at a dial setting. The 200 A rating holds flat from 40 °C through 50 °C ambient, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If your panel hits 55 °C near the breaker — common in a tightly packed enclosure with a transformer nearby — you lose 6 A of headroom. Plan the continuous load at 80 % of the derated value and you stay inside the thermal curve. It is a straight-ahead line-protection breaker with a remote-trip capability and a separate alarm contact for the maintenance PLC.
