Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you it handles high-fault-current service entrances and large industrial switchboards without cascading upstream. The TM240 overcurrent release is a thermal-magnetic unit, so it gives you inverse-time overload protection plus instantaneous short-circuit trip.
Above that, it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. If your panel runs hot, that derating curve decides whether this frame size works or you need a bigger one. It carries an undervoltage release (UVR) as standard — part number 3VA9608-0BB11 for the integrated auxiliary trip.
