The 25 A rating holds flat from 40 °C up to 50 °C; above that it derates to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C, so for a panel that runs warm the continuous load needs to stay under the derated curve, not the nameplate value. The interrupting ratings are the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. It carries two built-in auxiliary switches (HQ type) for remote status indication — no separate auxiliary module needed for basic open/closed signalling.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits a 3-pole SENTRON mounting base or direct panel-mount. No special cutout or adapter plate required for a typical distribution panel. The TM240 release is factory-set; no field adjustment of the thermal curve, so the trip coordination is fixed once the breaker is sized to the downstream load.
