Its rated continuous current Iu is 160 A, and the interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a 690 V motor circuit, the 11.9 kA rating still covers standard transformer-limited faults. The TM240 overcurrent release provides fixed thermal-magnetic protection: thermal for overloads, magnetic for short-circuits. Thermal derating is minimal up to 50 °C — the breaker carries 160 A at 40 °C, 45 °C, and 50 °C (–). Above that, it derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
The breaker occupies a 76.2 mm wide, 130 mm high, 70 mm deep footprint — standard 3-pole MCCB envelope for a 160 A frame. Mechanical endurance is rated at 15,000 operations, suitable for frequent switching in a distribution panel.
