It carries 160 A continuously at 40 °C ambient, derating to 150 A at 70 °C — the thermal curve governs the real panel load, not the 160 A headline. The interrupting ratings are the key fit check: 121 kA at 415 V and 75.6 kA at 440 V, so it handles high-fault downstream of a transformer or in a distribution board where SCCR demands are stiff.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for a 160 A frame. The shunt trip (STL) occupies the auxiliary slot; no undervoltage release is fitted. The basic switch order code is 3VA11165EF360AA0 for reference.
What the TM240 release means for coordination
The thermal element tracks cable heating; the magnetic instantaneous pickup is fixed at the factory. For selectivity studies, the 121 kA at 415 V and 75.6 kA at 440 V are the let-through values to coordinate with downstream breakers. Power loss is 38 W maximum at rated load — heats the enclosure, so account for it in a sealed panel.
