At 40 °C ambient the breaker is rated for 160 A continuous; that rating holds flat through 50 °C, then derates to 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C — so if your panel ambient runs above 50 °C, you need to apply the derating curve from the device manual. At 240 V it's rated for 187 kA; at 415 V it drops to 121 kA; at 440 V it's 75.6 kA; at 500 V it's 30 kA; and at 690 V it's 4.5 kA. The three-pole design fits standard 3-phase motor or feeder circuits.
Verify the mounting pattern against your existing panel layout.
