The 160 A continuous rating holds flat from 40 °C to 50 °C, then derates to 142 A at 70 °C, which matters for a packed enclosure where ambient climbs. Interrupting capacity runs 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V — so it handles high-fault utility feeds downstream of a transformer.
The shunt trip coil draws power from a separate control circuit; verify the voltage rating of the STL against your control transformer before wiring. Power loss maxes out at 33 W at rated load — account for that heat in the enclosure thermal calculation if you're stacking breakers tight.
