Its TM240 thermal-magnetic release handles overload and short-circuit curves without an external trip unit, and the integrated shunt trip (STL) allows remote tripping via a voltage trigger. The interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — figures that govern selectivity coordination downstream, not just the fault rating at the board.
Above that the curve steps down: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If the panel sits near a curing press or steam line, size the load side for the derated figure at your ambient — the breaker won't nuisance-trip, but it also won't carry a full 160 A into a 65 °C enclosure without margin.
The interrupting ratings step with system voltage: 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 400 V three-phase distribution board the 75.6 kA figure gives headroom for most transformer-fed fault levels.
The auxiliary contact block ships as two HQ-form switches, and the integrated shunt trip (order code 3VA9688-0BL33) is factory-fitted, not field-addable on this variant.
