The TM240 thermal-magnetic trip unit gives fixed thermal and magnetic settings — no field adjustment, which simplifies ordering but locks the curve to the factory calibration. At 240 V the interrupting capacity hits 187 kA; at 415 V it's 121 kA, at 440 V it's 75.6 kA, at 500 V it's 30 kA, and at 690 V it's 17 kA.
The breaker is rated 200 A continuously up to 50 °C ambient. Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The IP40 front protection means it's splash-safe from the front but not sealed; mount it in a clean, dry enclosure.
Power loss and compliance
Maximum power loss is 42 W at rated current — useful for enclosure thermal calculations.
