It includes a TM220 thermal-magnetic release and an undervoltage release.
This breaker's short-circuit breaking capacity is rated at 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That's a steep derating curve above 440 V, which is typical for MCCBs in this class — the arc extinction physics get harder as voltage climbs. For a 480 V system (common in North America), the 75.6 kA at 440 V is the closest published figure; expect the actual rating at 480 V to fall somewhere between that and the 17 kA at 500 V.
Thermal derating — it's 160 A only up to 50 °C
The continuous current rating holds at 160 A from 40 °C through 50 °C ambient, then begins to taper: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. That's a 6.25% drop from the 50 °C baseline to the 70 °C ceiling, which is relatively mild — the thermal-magnetic element is designed to track the conductor ampacity derating curve. If you're packing this breaker into a tightly enclosed panel with other heat sources, plan for the 150 A effective limit at the upper end. Power dissipation at full load is 40.5 W maximum — not negligible in a dense panel; factor that into your enclosure ventilation calcs.
