Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — numbers that govern selectivity coordination with downstream breakers in a distribution panel. The 160 A rating holds flat from 40 °C through 50 °C, then derates to 144 A at 70 °C, so the thermal curve matters when the breaker sits in a warm enclosure near other heat sources. This is a line-protection version (not motor-protection) with no voltage trigger, no phase-failure detection, and no communication function. The integrated auxiliary trip uses order code 3VA9608-0BB24.
The 76.2 mm width (three-pole) matches the standard SENTRON 3VA footprint for a 160 A frame — it occupies the same panel cutout as other 3VA breakers in this current class.
The TM240 release is thermal-magnetic, so short-circuit pickup is fixed; for adjustable electronic trip curves, a different 3VA variant would be needed. The 15 000 mechanical endurance cycles suit it for infrequent switching (main disconnect duty), not daily load-break operation.
